With the recent General Available of New Teams on Mac, there are changes that impact the management of some tenants regarding new Teams and Microsoft Teams classic (formerly Microsoft Teams).

 

Users can switch seamlessly between New Teams and Microsoft Teams classic via an in-app toggle.

However, there are effects on tenant management that administrators should be aware of.

  1. The first change is the bundle ID for Microsoft Teams, which looks as follows:The bundle ID for Microsoft Teams classic remains the same: com.microsoft.teams
  2. The bundle ID for Microsoft Teams (work or school) is: com.microsoft.teams2

Note: this is the same bundle ID for the preview version which was named Microsoft Teams (work preview)

 

MacOS .app file name changes with the recent General Available of new Teams:

  1. Microsoft Teams classic — formerly Microsoft Teams– changed from Microsoft Teams.app to Microsoft Teams classic.app
  2. New Teams– now officially Microsoft Teams (work or school) — changed from Microsoft Teams (work preview).app to Microsoft Teams (work or school).app

 

Important MDM scenarios these changes can impact:

If you have an MDM implementation that periodically checks whether Microsoft Teams is installed on a given Mac device in your tenant based upon the .app name, and then installs a version of Teams if it isn’t present, then you may find that devices can have two version of Teams classic installed on the device: Microsoft Teams and Microsoft Teams classic.

If this happens, it should not require any action to remove the duplicate old Microsoft Teams version. When the old Microsoft Teams version next updates, the machine will be left with a single Microsoft Teams classic version on the device.

 

Transition Timeline for Microsoft Teams Classic:

Daily users of the now Microsoft Teams classic, should have automatically received an update that changed the name of the app from Microsoft Teams to Microsoft Teams classic in September via built-in custom updater.

User who rarely open Teams should have recently received the update via Microsoft Auto-update which was released on 10/10/23
