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.
Please check “Teams/Skype Consumer chat and calling interop” on the public roadmap at microsoft.com/microsoft-365/roadmap?filters.. for updates.Anonymous commented
Please reinstate this feature, if S4B can do this, why not Teams? Skype Consumer is widely used in business. Can't move users from Consumer to Teams subscription if they suddenly loose all their external contacts! Multiple messengers are inconvenient for most.
