As stated in the last update, the ability to use multiple Teams accounts at the same time is being implemented in stages for Desktop. Faster tenant switching functionality on the Windows client has been rolled out to the public ring fully, and Mac will begin rolling out soon. Work is in progress on cross-tenant notification improvements, and support for multiple accounts on desktop will follow. We’ll keep you posted!
Note: The ability to use multiple Teams accounts at the same time is supported on iOS & Android today.
Alex & the Teams team
As the others a release date would be great.
Also I wonder about you said Alex : "Full multi-tenant, multi-user support will be added after fast tenant switching."
Does it means that while in a Teams call we will still not be able to switch to another tenant to check something without killing the call ?
Clearly this is mandatory. Uses cases : Internal company call & need to check a data on a customer teams. It happens everyday.
