The Set-MsolUserPrincipalName command will allow you to rename the UserPrincipalName of your Azure AD user account.
This can be useful in various scenarios.
One of the main reasons you’d want to use Set-MsolUserPrincipalName is to align your Office 365 UserPrincipalName with your on-premises UserPrincipalName.
There are many good reasons to keep your UserPrincipalName aligned in on-premises Active Directory and Azure AD. If, e.g., you use a domain suffix on-premises that hasn’t been verified in Office 365, you can get some “funny” results.
Whatever the reason, this is how to run it.
How to Rename the UserPrincipalName Attribute in Azure AD
You can use the ObjectId or the UserPrincipalName to identify the object you want to rename.
In any case, make 100% sure you’re addressing the correct object, e.g., by extracting the naming information:
PS C:\> Get-MsolUser -UserPrincipalName lene.hau@azure.skrubbeltrang.com | fl *name*,ObjectId DisplayName : Lene Hau FirstName : Lene LastName : Hau SignInName : lene.hau@azure.skrubbeltrang.com UserPrincipalName : lene.hau@azure.skrubbeltrang.com ObjectId : 2df91b7a-78a7-47cf-b58c-e294f302fd71
The following example shows how to execute the Set-MsolUserPrincipalName command using the UserPrincipalName as the identifier:
Set-MsolUserPrincipalName -UserPrincipalName lene.hau@azure.skrubbeltrang.com -NewUserPrincipalName lhau@azure.skrubbeltrang.comThis example shows how to execute the Set-MsolUserPrincipalName command using the ObjectId as identifier:
Set-MsolUserPrincipalName -ObjectId 2df91b7a-78a7-47cf-b58c-e294f302fd71 -NewUserPrincipalName lhau@azure.skrubbeltrang.comHow to Bulk Rename Azure AD UserPrincipalName
What if you’re facing a general problem and need to rename the UserPrincipalName of many users?
The below example will identify all Azure AD users with a UserPrincipalName ending with “@easy365manager.onmicrosoft.com” and replace it with “@easy365manager.com”:
$Users = Get-MsolUser | ? {$_.UserPrincipalName -Like '*@easy365manager.onmicrosoft.com'}
ForEach ($User In $Users){
Set-MsolUserPrincipalName -ObjectId $User.ObjectId -NewUserPrincipalName $User.UserPrincipalName.Replace("@skrubbeltrang.onmicrosoft.com", "@easy365manager.com")
}Please take a good look at the $Users variable before executing it, and use it at your own risk!
