We know you are patiently waiting for this feature. This feature is being implemented in stages. Fast tenant switching is currently in testing both internally and with early customers. We expect to release to the public in the Fall. I’ll post an update once it’s rolling out.
Full multi-tenant, multi-user support will be added after fast tenant switching.
@Erik, Yes that linkedin post works, but it just packages the web app into a separate application. Unless I'm doing something wrong, it still only allows 1 desktop client to run, then runs another 'web instance' of Teams in this application. If I wanted that all I'd have to do is open Edge, Chrome, Firefox and sign in to Teams Web App with a different user. We've been doing that for a long time. The notifications are terrible in the web app, and screen-sharing is not allowed. Again, maybe I'm doing something wrong, but how this turned out was not useful. Still looking for a way to run two desktop instances of Teams to allow multiple logins, or just have Teams allow multiple accounts...Thanks
