Migrating Skype4B on-prem user to Teams

David Christensen

I have a subset of Skype4B users where their SIP domain does NOT match their primary SMTP address domain.

SIP- @domA.company.com

SMTP- @company.com


Skype4B has been configured for hybrid and @domA.company.com is listed as an organization domain.


Can these users be migrated safely to Teams? Will there be any issue with Federation?  Teams-Teams or Teams-Skype4B?

I can't see that there should be any technical problem, since it is working with you Skype hybrid everything should be prepared. I know about companies using different email and SIP addresses in Teams. But the issue is that is harder to find your users when they don't have the same email and SIP address.
