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.

The lack of integration across multiple tenancies becomes a huge issue for groups of companies where there's an attempt to rollout a common collaboration platform for all entities of the group. We are at that stage and hitting a roadblock with MS Teams.
