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 -UserPrincipalName dfranks@exchangetest.com -NewUserPrincipalName Dave.Franks@exchangetest.com
The above command would be run using powershell once you established a connection with office 365. However that command would not "update" the same users UPN in the On premise environment, so how does running that command make any sense?
Isn't it just smarter to rename the Object using ADUC? Were you not previously able to use that tool to rename UPNs for Office 365 users?
Thanks,
Robert

Not sure if you have a solution to this yet but it took me a while.
I ended up moving the user to an OU that wasn't synced.
I ran AD sync
This puts the user in the deleted section at admin.microsoft.com
I restored it making it a cloud only account and and then I modified the username@domain.onmicrosoft.com address
moved the user back to the original OU
Ran Sync
It fixed it
Before all this I had already modified the username, mail, email, mailnickname, proxyaddresses, targetaddress, and UserPrincipalName in AD but nothing would modify the username@domain.onmicrosoft.com address.
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?
- Ok so is the correct process to rename the user account in AD and then run the command for the office 365 side ?
