How to change user principal name on Azure AD

Question

I'm trying to change the user principal name on my Azure AD user using a PowerShell command Set-MsolUserPrincipalName that I found in the Microsoft documentation here. This works fine and changes the user principal name, but it also changes the email property to the same value as well.

Example command:

Set-MsolUserPrincipalName -UserPrincipalName "[email protected]" -NewUserPrincipalName "[email protected]"

Is there another way to change the user principal name without affecting the email of the user?

Answer 1

There is no way to change the user principal name without affecting the email of the user. The mail property is read-only, and the principal name should map to the user's email name.
