works also for us now, by updating program to the last version.
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
We need this feature, it's very important to collaborate with external users. When I discovered that it wasn't possible, I thought... it's a big bug ****! I don't belive. Please develop it to help collaboration between the companies.
Good news! This is in the works.
Please we need this feature!
Please check “Teams/Skype Consumer chat and calling interop” on the public roadmap at microsoft.com/microsoft-365/roadmap?filters.. for updates.
