Classic Teams to New Teams Migration

On March 31st New Teams will begin replacing Classic Teams on all University computers.

A new version of Microsoft Teams is replacing the current version of Teams installed on computers.  It is likely that the new version was already automatically installed on your computer or you have been prompted to make the switch by Teams already.  The previous version of Teams is now referred to as Classic Teams and the new version is referred to as New Teams.  

Both versions of Teams may be installed at the same time on your computer and you can choose with version to launch or which to make the default version. The option to launch Classic Teams is only available for a limited time during the migration period.

It is suggested that you begin using the version of Teams with the "new" label on the icon as it will be the default version moving forward. If you are launching New Teams for the first time you will be prompted to make the switchover to New Teams.

Once you are using New Teams there is an option in the client that you can toggle to switch back over to Classic Teams.  Again, this is only for a limited time during the migration and will eventually go away.

New Teams changes and issues affecting our tenant



Adding Box to Teams channels no longer functions via Microsoft's Add Cloud Storage option. As it only supports OneDrive at this time. Method 1 in this kb currently works in New Teams to add Box to a Team's tab:
Adding a website to a Team with the Website app may sometimes fail to render or say something went wrong. This is mostly relevant to websites that require authentication including Box and Planner. Microsoft has provided a document detailing the website and its inability to not display websites correctly with the only work around being to open the website in a browser:
MP50 integration with New Teams on MacOS is officially unsupported by Microsoft.  Only the audio inputs/outputs will work.   Microsoft hopes to provide support in the future, but as of now there is no solution for this issue. 
MP50 integration with Windows is suffering from several deficiencies in button interop and call control.   There is an existing ticket with Microsoft to fix these issues.  Fixes to many issues are expected in early April. 
Better Together over Bluetooth integration between all models of IP Phones (Yealink and Poly) and New Teams does not work. This is a Windows only feature.   Microsoft is aware of the issue and hopes to have this resolved sometime in April.
