Rename users UPN, Hybrid Enviornment
Hey Team,
Couple of questions here are regarding renaming a users UPN in a Hybrid Environment. I understand you can use the following command:
Set-MsolUserPrincipalName -UserPrincipalNam...
You should be making the change on-premises. In case the UPN change does not get reflected in O365 (happens sometimes), then you can use the cmdlet. You can also change the UPN directly in O365, without changing it On-Prem. But as the on-premises AD is the source of authority, you risk the change getting overwritten at some point (when a Full sync cycle is invoked).
Whats the easiest way to first change the UPN name on the Prem server. also use PS?
