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
I agree I don't want fast switching. I want one instance of Teams to support multiple accounts within the same interface. I'm a consultant that has multiple Teams accounts from O365. I want it to function like Outlook where I can have multiple accounts connected and I'd get notifications from any of those from the one Teams app interface.
Any update on timing?
