Ive been troubleshooting an issue where the Microsoft Teams meeting addin for Outlook was formatting Teams meeting very oddly.

Example of this issue when scheduling a new Teams Meeting in Outlook

all the urls work correctly but its not formatted correctly with the “Join Microsoft Teams Meeting” link

This is what it should look like

What ive found is that the Teams Meeting Addin looks to have dependency on the Outlook VBA addin for the formatting. The VBA addin is unloaded and loaded when you click “new Teams Meeting” in Outlook.

When viewing the Add-in’s from File>Options>Add ins in Outlook i could see Microsoft VBA for Outlook Add-in was listed as disabled application add-in

This had been disabled in Outlook via GPO and only listed Add-ins were allowed and VBA was not allowed. If you enabled the VBA add-in for Outlook then the Teams Meeting is formatted correctly.

 

Hope this helps someone.
