External Contacts showing up as UPN
We have our tenant open so that we can message users from other tenants as we work on projects. Recently on of our users has noticed that when they add external users as contacts, they're showing up ...
That's the expected behavior, Exchange is the only workload that uses the primary SMTP as identifier. If anything, you should expect Teams to use the SIP address, but MS made a decision to stick to UPN.
Interestingly, I'm finding a different situation on this. I just opened up Teams, went to a Guest account view (I'm the guest of another tenant). I then went to Chat, started a new message to someone that I hadn't previously chatted at the other tenant. His UPN and Primary Email are different ... and when I went to look him up, I couldn't find him by his UPN (which is also listed as a smtp proxy address). But, when I typed in (again for the recipient in the chat) the primary email instead, he came right up. And, in addition, if I type another (a 3rd one) alias, it doesn't come up.
Even more interesting, when I go into a SEPARATE account that I have onto the other company's tenant, where I'm setup as a global admin, and I go into Teams there, and start a new chat ... and I type in ANY of the above (UPN, primary email, and 3rd alias), all of them are found immediately.
Seems this is inconsistent with what was said above -- right?
