Teams has started displaying some Microsoft Adverts for What's New in Teams and Conferences. This can be annoying to users who just want to use Teams. The latest version of MicrosoftTeams PowerShell has introduced a methods of disabling those messages from being displayed.
To do so first ensure your MicrosoftTeams PowerShell module is v6.1 or higher:
get-module MicrosoftTeams
To update the PowerShell module use command: Update-Module MicrosoftTeams -RequiredVersion 6.3.0 -Force
If updated then restart PowerShell and run the following:
Get-CsTeamsUpdateManagementPolicy -Identity Global
Check what is returned for DisabledInProductMessages
To set run the folowing:
[array]$DisabledMessages = "edf2633e-9827-44de-b34c-8b8b9717e84c", "91382d07-8b89-444c-bbcb-cfe43133af33"
Set-CsTeamsUpdateManagementPolicy -Identity Global -DisabledInProductMessages $DisabledMessages
That should now apply to all tenant users :-)
