Change Teams default login
DaGbyte Hi David, would it be an alternative to prevent the automatic population of the UPN? If applicable you can use this reg key.
Turn off pre-population of the UPN:
Computer\HKEY_CURRENT_USER\Software\Microsoft\Office\Teams
SkipUpnPrefill (REG_DWORD)
0x00000001 (1)

Thanks for this! Do you happen to know if there is a regkey to make it use the user's e-mail address by default instead of UPN? We also have non-routable UPNs so stopping it from pre-populating the UPN is definitely helpful. I'm just wishing there was a way I could pre-populate the e-mail though.
- Hi, I am afraid not. But they do recommend that upn and primary smtp match. Teams will always default to the domain-joined account if one sign out och restart.
