Chatting with cross-tenant synchronization
We have implemented the new cross-tenant synchronization feature (https://learn.microsoft.com/en-us/entra/identity/multi-tenant-organizations/cross-tenant-synchronization-overview). Now, every user has his "own" account in his home tenant, plus the synchronized account in other tenant. So, imagine I am UserA in TenantA, and I want to chat with UserB in TenantB. In my Teams (New Teams), when I search for UserB, I find two entries: "UserB" which is the synchronized account in my tenant (TenantA) "UserB (External)" which is his account in his own tenant (TenantB) I can select both and chat with both, due to New Teams' multi-tenant feature. However, UserB sees my chat only if I use his home tenant account. If I chat with "UserB" (his synchronized account in my tenant), he never sees that in his Teams, unless he manually switches to TenantA. Same for me, if UserB chats with "UserA (External)", I see this in my Teams. But if he chats with "UserA" (my synchronized account in his tenant), I never see that. Is there anything we can do?
