Ill try and summarize some but it will be hard

Fixes Cause and Fix
4458680

    Skype for Business Web App or Skype Meeting App doesn’t respect conferencing policy for AllowParticipantControl and AllowExternalUserControl
In a Microsoft Skype for Business Server 2015 environment, an anonymous participant joins a Skype for Business meeting by using the Skype for Business Web App or Skype Meeting App. Even though the conferencing policy (where AllowParticipantControl and AllowExternalUserControl are both set to False) doesn’t enable participants to take control, the participant can give control to other users in the meeting and bypass the conferencing policy.

Note This fix only applies to Skype Meeting App. If you are using the Skype for Business Web App, you have to enable the Skype Meetings App to replace the Skype for Business Web App.

To enable the Skype Meetings App, please run the following cmdlet:

Set-CsWebServiceConfiguration -MeetingUxUseCdn $True

4458689

    Skype for Business on Mac can’t save a password when AllowSaveCredentials is False and “Keep me signed in” is selected
In a Microsoft Skype for Business Server 2015 environment, you create a Skype for Business mobility policy in which the AllowSaveCredentials parameter is set to False. In this scenario, users can’t save their credentials information (such as passwords) on their mobile devices. However, when a user tries to sign in to Skype for Business by using the Skype for Business on Mac desktop client, the password is also not saved even if the user selects the Keep me signed in option on the client. It’s expected that the Skype for Business on Mac desktop client can save the sign-in credentials.

The issue occurs because the mobility policy was applied to the Skype for Business on Mac desktop client, and it was by design. After you apply this update, the mobility policy is applied only to the mobile clients.

4464370 Skype for Business UCWA clients can’t be distinguished on CDR report if connection is internal or external In a Microsoft Skype for Business Server 2015 environment, you use a Skype for Business UCWA client that’s in an external network to start a call with a Skype for Business client user. You may find that the value of Is From user internal always shows Yes on the Call detail recording (CDR) report. It’s expected that the clients should be flagged correctly as external or internal on this report.
4458698 Notify Skype for Business on Mac and mobile users that the conversation is an interop conversation in Skype for Business Server 2015 The interoperability of Microsoft Teams and Skype for Business enables users in the same organization to make one-on-one voice and video calls or chat. However, there’re some limitations about the interop experience, such as screen sharing (desktop or app sharing), file transfer for two-party chats, and so on. For a richer experience, users may have to know the client that the other side uses. After you apply this update, Skype for Business on Mac and mobile users can be notified that it is an interop conversation when users are in a one-on-one chat or call.

 

4345985 “Failed to setup database rtcxds” error when you upgrade the SQL Server 2008 R2 back-end database in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you use Microsoft SQL Server 2008 R2 as a back-end database. After you install the July 2018 cumulative update 6.0.9319.534 (CU7) for Skype for Business Server 2015, you may find the SQL Server database can’t be upgraded. In addition, you may receive an error message that resembles the following:

Failed to setup database rtcxds due to an unexpected error.

Detail: Microsoft.SqlServer.Management.Smo.UnknownPropertyException: Cannot write property TargetRecoveryTime.This property is not available on SQL Server 2008 R2.

 

This issue occurs because a value of targetRecoveryTime attribute isn’t set correctly, and it isn’t present in SQL Server 2008 R2.

4132306 Invitee visibility delay when a UCMA application uses AudioVideoMcuSession.BeginDialOut to create a conference In a Microsoft Skype for Business Server 2015 environment, you use a Unified Communications Managed API (UCMA) application to schedule an audio or video conference and dial out a PSTN number from the conference by using the AudioVideoMcuSession.BeginDialOut method. After the UCMA application performs the dial-out operation from the Audio/Video Multipoint Control Unit (AVMCU), the invitee accepts the call and joins the conference successfully. However, the conference organizer or other participants could not immediately see the invitee through the UCMA application. It may delay for four to five seconds. It’s expected that the invitee can be visible in less than one to two seconds.
 4458688 Support to prevent external file transfer especially for Skype for Business on Mac users in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you create a file transfer filter configuration for the Edge Server to block a user’s ability to transfer certain type files by using a Skype for Business Server client in an external network. When a Skype for Business Server client that’s enabled by Microsoft Unified Communications Web API (UCWA), such as a Skype for Business on Mac client, is externally talking to an internal client, you may notice that it doesn’t honor the file transfer policy as configured.

This issue occurs because the external file transfer’s traffic doesn’t traverse the Edge Server. Therefore, the external file transfer is enabled.

4458695 QoE Call Detail SubReport shows a wrong caller/callee connection type in Skype for Business Server 2015 In a Skype for Business Server 2015 environment, you successfully make a telephone call with another Skype for Business user by using your mobile phone on mobile cellular network. Then you open the details of this session in the User Activity report. You may notice that the caller connection type is displayed as Tunnel (VPN) instead of MobileBB (Mobile Broadband) in the QoE Call Detail SubReport (which is a part of Media Quality report).

This issue occurs because the connection type of MobileBB and Tunnel is interchanged.

4459712 Update parameters of Move- CsUser in Skype for Business Server 2015 After you apply this update for Microsoft Skype for Business Server 2015, the irrelevant parameter ConcurrentMovesPerFE will be removed from the Move- CsUser cmdlet. In addition, the following parameters are reordered so that they can first appear when you press the Tab key through them:

  • Identity
  • Target
  • Credential
  • MoveToTeams
4458691 Optionally turning on/off the OAuth protocol is available in Skype for Business Server 2015 After you apply this update, the Skype for Business Server 2015 OAuth (Open Authorization) protocol for server-to-server authentication and authorization can be optionally switched by using PowerShell.

For example:

Move-CsUser -Identity “UserAccountName” -Target “RegistrarPool FQDN” – UseOAuth

In this example, the OAuth authentication method is invoked when you move the user account by using the Identity to the Registrar pool. Otherwise, the Skype for Business Server will use the existing legacy authentication.

4458694 New trusted application endpoints are always assigned to the same routing group in Skype for Business Server 2015 When you create multiple new endpoint contacts one after the another for a trusted application in Microsoft Skype for Business Server 2015, the endpoints will always be assigned to the same routing group against the same Front End Server. If the Front End Server goes down, all the endpoints will go into “reestablishing” state. Then, the Front End Server will be overloaded and meetings will be affected. It’s expected that the endpoints that’re created will be assigned to different routing groups to balance the load.

This issue occurs because the routing group IDs for trusted application endpoints don’t populate correctly.

4458676 Busy Options settings are removed if you change the Call Forwarding settings with a mobile device or third-party phone device in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, consider the following scenario:

  • You set the Busy Options feature to Busy on Busy or Voicemail on Busy status by using the Set-CsBusyOptions cmdlet.
  • You verify that the Busy Options is turned on by using the Get-CsBusyOptions cmdlet.
  • You sign in to the Skype for Business for iPhone or Android client. Or, you sign in to the Skype for Business client by using a third-party phone device such as Polycom, Spectralink and so on.
  • You turn on the Call Forwarding.
  • You run the Get-CsBusyOptions cmdlet to check the Busy Options status.

In this scenario, you can see the Busy Options settings that you set before are lost.

 

4458679 Inactive RGS workflow that has deleted queues can’t be imported by Import-CsRgsConfiguration in Skype for Business Server 2015 In a Skype for Business Server 2015 environment, you can’t run the Import-CsRgsConfiguration cmdlet to import the Response Group configuration data that was previously exported by using the Export-CsRgsConfiguration cmdlet. This issue occurs in the following two scenarios:

  • You force the deletion of the queues that the workflow uses by using the Remove-CsRgsQueue -Force cmdlet.
  • You set the RGS workflow to inactive and configure it for “Managed.”

When you remove the queues, the workflows that use these queues become inactive and Skype for Business Server can’t find the queues referenced by these inactive workflows. Therefore, the import cmdlet fails.

4458686 Configuring a watcher node test user fails in the German version of Skype for Business Server 2015 Consider the following scenario:

  • You implement the German version of Microsoft Skype for Business Server 2015 in a German language operating system of Windows Server.
  • You configure a watcher node test user by using the Set-CsUserTestCredential cmdlet.

For example:

Set-CsTestUserCredential -SipAddress “sip:user@contoso.com” -UserName “contoso\user” -Password “<Password>”

In this scenario, you receive an error message that resembles the following:

Set-CsTestUserCredential : Fehler beim Festlegen der Anmeldeinformationen f.r sip:user@contoso.com. Innere Ausnahme: Microsoft.Rtc.Management.SyntheticTransactions.CredentialManagement.NetworkServiceImpersonator+NetworkServiceImpersonatorException: Fehler beim Annehmen der Identit.t des Netzwerkdienstkontos. Fehlerdetails: Es wurden keine Prozesse im Besitz von ‘NT Authority\Network Service’ gefunden..

4458684 Local Configuration Store can’t be installed when disabling TLS 1.0/1.1 in Skype for Business Server 2015 When you install the Local Configuration Store by using the Microsoft Skype for Business Server 2015 deployment wizard, the installation fails, and you receive the following error message:

Prerequisite installation failed: Prerequisite installation failed: SqlInstanceRtcLocal For more information, check your SQL Server log files. Log files are in the folder C:\Program Files\Microsoft SQL Server\MSSQL*.RtcLocal\MSSQL\Log, where the * represents your SQL Server version number. For example, SQL Server 2012 uses this path: C:\Program Files\Microsoft SQL Server\MSSQL11.RtcLocal\MSSQL\Log.

In addition, an Event ID 26011 could be logged in the Event Viewer. This issue occurs when you enable the TLS 1.2 and disable the TLS 1.0/1.1 on the operating system.

This issue occurs because the setup installs a version of SQL Express that does not support TLS 1.2.

You have to enable TLS 1.0 and TLS 1.1 on the local computer; uninstall Microsoft SQL Server 2014 (64-bit) through Programs and Features in Control Panel, and then rerun step 1 – Install Local Configuration Store and step 2 – Setup or Remove Skype for Business Server Components. After that, update SQL Server to the version that supports TLS 1.2, and then disable TLS 1.0 and TLS 1.1 again after SQL Server is updated.

4343061 Event ID 1000 (0xc0000005) and RtcSrv.exe of the SBA/SBS crashes after startup in Skype for Business 2015 and Lync Server 2013 onsider the following scenario:

  • One or more Survivable Branch Appliances or Survivable Branch Servers (SBAs/SBSs) are deployed in a Microsoft Skype for Business 2015 or Lync Server 2013 environment.
  • The servers interact with a trusted application (typically UCMA-based) that queries the presence information for users who are homed on these SBAs/SBSs.

In this situation, when some users’ presence information is queried, the Lync Server Front-End service (RtcSrv.exe) of the SBAs or SBSs starts but then crashes within about 20 seconds. Additionally, you receive an event that resembles the following:

Time: Date

4458683 Can’t switch the meeting audio to a UCWA client in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you try to transfer audio to a UCWA client such as Skype for Business for iOS during a meeting. However, the audio transfer fails. It’s expected that the conference including the audio can be switched to the UCWA client in the correct way.

You can rejoin the meeting from the UCWA client.

4458682 “Failed creating application activity” error when you use the Test-CsUcwaConference cmdlet in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you run the Test-CsUcwaConference cmdlet to verify that a pair of users can schedule, join, and then conduct an online conference by using the Unified Communications Web API (UCWA). You may find the test fails and the outputs return a “Failed creating application activity” error message. For example:

$cred1 = Get-Credential “CONTOSO\User1
$cred2 = Get-Credential “CONTOSO\User2
Test-CsUcwaConference -OrganizerSipAddress sip:User1@contoso.com -OrganizerCredential $cred1 -ParticipantSipAddress sip:User2@contoso.com -ParticipantCredential $cred2 -TargetFqdn pool.contoso.com
Target Fqdn: pool.contoso.com
Target Uri:
Result: Failure
Latency: 00:00:01.3141048
Error Message : Failed creating application activity.
Inner Exception:One or more errors occurred.
Inner Exception:One or more errors occurred.
Inner Exception:Object reference not set to an instance of an object.

The commands that are shown here test the ability of a pair of users (CONTOSO\User1 and CONTOSO\User2) to participate in a UCWA online conference.

4458677 Escalation to LBR VoIP user fails when a same site LBR user is in a P2P call with a PSTN user in Skype for Business Server 2015 Consider the following scenario:

  • You’re a Location-Based Routing (LBR) enabled user and located on a LBR enabled site in Microsoft Skype for Business Server 2015.
  • You successfully start a peer-to-peer call with a public switched telephone network (PSTN) user by using the Skype for Business on Mac client.
  • Then you escalate the peer-to-peer call to a conference by inviting another Voice over Internet Protocol (VoIP) user who is located on the same site as you.

In this scenario, you may notice that the user can’t be reached because of conferencing service issues. It’s expected that the user can join the conference without any problem as the escalation happens to the same site’s user only.

4458693 Can’t join a LBR enabled conference after a user uses the “Call me at” feature in Skype for Business Server 2015 You’re hosted on a LBR (Location-Based Routing) enabled pool of Microsoft Skype for Business Server 2015. When you initial a conference call, if one of the participants joins the call by using the “Call me at” feature for his local meeting room device such as Polycom Trio, the later participants can’t join the conference by using a Skype for Business client. However, they can dial in by using PSTN to join the meeting.

 

4458697 Skype for Business Front-End servers connecting to Exchange online for OAuth doesn’t use proxy server Consider the following scenario:

  • You are in a Microsoft Skype for Business Server 2015 on-premises and Exchange hybrid environment.
  • You implement the Skype for Business Server 2015 Front-End pools with the proxy and without a direct access to the Internet.
  • You set up the Skype for Business Server OAuth configuration settings (-ExchangeAutodiscoverUrl-) pointing to your on-premises Exchange CAS server.
  • You enable the server-side conversation history feature by using the conversation history configuration settings for Skype for Business.
  • You set up an account by creating an Exchange online mailbox.

In this scenario, the user of the account can’t use the feature of server-side conversation history to save the conversation history in the Exchange online mailbox. In addition, the on-premises users won’t be affected.

The issue occurs because the Exchange CAS server is redirecting the Autodiscover request to Exchange Online directly instead of using the proxy server. As the Exchange on-premises servers can’t directly connect to Exchange Online, the connection fails.

In addition, as the on-premises mailboxes are local resource, the Autodiscover process works fine.

4458692 Incorrect caller ID is shown on the Skype for Business client in a call-forwarding scenario Consider the following scenario:

  • You implement a third-party SIP-Trunk integration solution such as Cisco, Avaya Aura and so on, with Microsoft Skype for Business Server 2015.
  • You are an enterprise voice (EV) enabled Skype for Business user. User B and User C are using the Cisco or Avaya phone.
  • User C has a call forwarding to User B.
  • You make a telephone call with User C by using the Skype for Business client.
  • The call connection is established between you and User B.

In this scenario, you may see the Skype for Business client displays the User C’s caller ID (also known as a Calling Line ID) instead of User B’s caller ID.

This issue occurs because the information about the original caller is lost at the Skype for Business Mediation server.

4458690 RGS call forwarding to a queue or SIP address not working in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you set the Call Action feature to Forward to another queue or Forward to SIP address for a response group queue. When a user calls this response group (RGS), the call is stuck in the queue until it’s hung up and not forwarded to the queue or SIP address as configured.
4464374 Can’t create a Skype meeting on behalf of someone else by using the Outlook for Mac client in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you can’t create a Skype meeting on behalf of a specific user in the Outlook for Mac client. In addition, the Outlook on the web (formerly known as Outlook Web App) client and the Outlook for Windows client aren’t affected.
4464375 The Test-CsPhoneBootstrap and Test-CsClientAuth cmdlets not working in Skype for Business Server 2015 that’s installed on Windows Server 2016 You can’t run either the Test-CsPhoneBootstrap or Test-CsClientAuth cmdlet against a particular user’s SIP address in Microsoft Skype for Business Server 2015 that’s installed on Windows Server 2016. For example:

Test-CsClientAuthentication -TargetFqdn <FeFqdn> -UserSipAddress <UserSIP> -UserCredential <UserCred> -Verbose

The cmdlet fails and you may receive an error message that resembles the following:

“Unable to perform authentication of credentials. Inner Exception:ComputeSignature failed.”

4464372 Skype for Business Server 2015 UCMA services crash on service startup when running on Windows Server 2016 This update fixes the issue that the Microsoft Skype for Business Server 2015 UCMA-based services, such as Skype for Business Server Audio/Video Conferencing Unit (AVMCU), Skype for Business Server Application Sharing (ASMCU), Skype for Business Server Conferencing Auto Attendant (CAA), Mediation Server and so on, may crash on service startup when running on Windows Server 2016. The crash has a call-stack that’s similar to the following:

4464371 Support Rate my Call feature for Skype for Business UCWA clients in Skype for Business Server 2015 After you apply this update, Microsoft Skype for Business Server 2015 will enable Skype for Business on Mac clients and Skype for Business mobile clients to use the Rate my Call feature that provides a way for enterprises to achieve feedback from end-users. To get this update, install the January 2019 cumulative update 6.0.9319.537 for Skype for Business Server 2015, Web Components Server and the January 2019 cumulative update 6.0.9319.537 for Skype for Business Server 2015 and Unified Communications Managed API 5.0 Runtime.
4458678 Skype for Business VbSS application sharing not working for UCMA based Contact Center in Skype for Business Server 2015 Consider the following scenario:

  • You implement the Microsoft Skype for Business UCMA based Contact Center applications that support app sharing in your organization.
  • You enable the Video-based Screen Sharing (VbSS) feature in Skype for Business Server 2015.
  • You share your desktop with another user by using a Skype for Business client.

In this scenario, the desktop sharing fails.

4458687 “An error occurred during this screen presentation” error occurs in VbSS application sharing conference in Skype for Business Server 2015 In a Microsoft Skype for Business Server 2015 environment, you apply the March 2018 cumulative update for Skype for Business Server 2015 and enable Video-based Screen Sharing (VbSS) in Skype for Business. In this scenario, when you try to share your desktop during a conference, you may receive the following error message:

An error occurred during the screen presentation.

 

4470530 Can’t make an outbound PSTN call by using Skype for Business on Mac if LBR is enabled In a Microsoft Skype for Business Server 2015 environment, you’re located in a network site that’s enabled for Location-Based Routing (LBR). When you make an outbound PSTN call by using a UCWA client such as a Skype for Business on Mac client or a Skype for Business mobile client, the call fails. In addition, the Skype for Business for Windows client isn’t affected.
4470531 Support moving users from on-premises to Teams in Skype for Business Server 2015 After you apply this update, Microsoft Skype for Business Server 2015 will support migrating your on-premises users to Teams. To get this update, install the following updates:

4464373 Can’t escalate a peer-to-peer call to a conference if VbSS is used in screen-sharing in Skype for Business on Mac In Microsoft Skype for Business Server 2015, when a Skype for Business on Mac client user tries to add a new participant to a peer-to-peer call that has a screen sharing by using the Video-based Screen Sharing (VbSS) feature, you may find the escalation fails and the participant can’t receive the meeting invitation to join the peer-to-peer session.

  1. Do you get an XDS version mismatch when running Test-CsDatabase – Localservice?

    ExpectedVersion : 10.15.5
    InstalledVersion : 10.15.4

  2. After installing this CU update in our environment last month we have an increase of issues with our Mac users (relative small group of users but all seem affected, all using latest skype client version).
    They have issues with receiving and sending IM’s (the im was not sent), issues with audio and with calling. This is P2P but in a federated environment. Have you heard anything about this? I cannot find any information online but I cannot pinpoint the problem on our end.

  3. Also introduces a few issues form what we have seen:
    SLA – Call Forward takes delegates Call Forward settings
    SLA – Unable to forward to PSTN number
    If you depend on SLA, postpone! MS states one fix will probably not make it until CU10!

    Cheers,
    Jeffcsp

    1. Thanks for sharing the info Jeff. Have you opened a case with Microsoft for this ? There is a March 2019 CU recently released but waiting for details on whats included. Thanks Martin
