Azure AD for Office 365 updating e-mail address

[nicholab]

How do I change a user e-mail address in office 365 when synchronised with on site AD. I have updated the e-mail in the onsite AD but the e-mail address still gets listed as the old one.

You need to edit the proxy address attribute on the user account. use SMTP (uppercase) for the primary address smtp (lower) for any additional alias. To see the attribute, you will need to turn on the advanced AD settings, and enter the user account settings.

^ It can also take a good while to propagate across their infrastructure. I swapped a couple of test accounts to see how well it worked and Leeloo Dallas Multipass was still Tony Stark in quite a few places for days afterwards and I don't think URLs have ever been updated for OneDrive etc. Edited September 8, 2017 by pete

Powershell procedure:

 

1. Open Azure AD module for Windows Powershell
   
2. Connect-MSOLService
   
3. Input Global admin credentials
   
4. set-msoluserprincipalname -newuserprincipalname [email protected]ing -userprincipalname [email protected]ing
   
5. Update display name in AD/365 admin centre if needed.
   
6. Check results: Get-MSOLUser -userprincipalname [email protected]ing | Select-Object *

This wouldn't work for the OP as he is syncing from local AD. Besides setting the User Principal Name is the login address not email.

Update it on local AD then run the above procedure. UPN's are the same as proxy address here so apologies if this may not be the case elsewhere. Updating UPN updates proxyaddress does it not?
