Unable to switch to New Teams (work and school) (FIXED!)

Copper Contributor

Ahead of the April 1st switchover, I have a user with a rather peculiar issue: he is facing this banner when trying to change to the New Microsoft Teams (work and school): "Something went wrong, and we couldn't open the new teams. Please try again."



Steps tried to resolve: 


  • Cleared the Classic Teams cache

  • Cleared the New Teams cache

  • Added a Reg_Dword to registry (BlockNonAdminUserInstall) Set value to 0
    Registry path: Software\Policies\Microsoft\Windows\Appx

The above steps did not work. 



Uninstall Teams Classic

Online Repair of Microsoft 365 suite (which now includes MS Teams) resolved the issue entirely.
