How to Change UPN Names and SMTP Addresses in Active Directory with PowerShell?

Definitely! We had to change our domain when transitioning to Azure. Just a heads up that if your onboarding system doesn’t support bulk updates, you might need to run the script multiple times or change UPNs manually during user creation. AD doesn’t allow you to set a new default easily.

I totally understand wanting to ask! My PowerShell skills are basic too, but I often run into issues with CoPilot. It sometimes fixes bugs only to create new ones. Microsoft seems to be having some difficulties lately, huh?

Honestly, if you just Googled this, you’d get a script from Bing or something in no time! But hey, I get it—it’s always good to double-check things.

Yeah, it's actually pretty easy! You can use the 'Set-ADUser' cmdlet to do that without too much hassle.
