Microsoft Teams – How to join and enable Public Preview for your users

First off what is Public Preview ?

Public Preview for Microsoft Teams allows you early access to unreleased features in Teams, these features are not yet general available (GA) to everyone so you have early access to try and test before they are GA.

We early access you can test them for yourself and your organisation before they are rolled out to all your users, you can also provide feedback to Microsoft.

Also note, features in Public Preview might not be fully complete and are subject to change when they are released to everyone but you have early access.

If one person registers for Public Preview does that mean all users in the same tenant are enabled for Public Preview ?

No, its a per user basis.

Also some features will require a friend who’s also enabled for Public Preview to test with as well.

How do you enable a user for Teams Public Preview ?

This is enabled via the Microsoft Teams Admin Centre via a policy so an administrator will need to enable this for the users that want to be part of Public Preview.

Please note – The default Teams update policy option is set to automatically enable Teams Preview features for any user enrolled in Office Current Channel (Preview). Info on current channel (preview) – as you may want your preview users to also be enabled for Office and then by default preview features in Teams would be enabled with requiring a custom update policy in the steps below.

If you only want Teams preview then create the custom update policy below.

If you want to disable Teams Preview for Office current channel (preview) users then you can follow the steps below and set the update policy to Not enabled.
