Powershell script to change User Principal Name to Primary SMTP Address

October 2nd, 2013 6 comments

When you install Exchange in environment you want to allow users to log into mails using their e-mail address. If your domain name is different from your e-mail domain, you have to add UPN suffix first. More abour it HERE. Then you need to change User Principal Name into Primary SMTP Address. I wrote little script to do so:

Get-Mailbox |
  ForEach-Object{
   Write-Host “For: ” + $_.SamAccountName
   Write-Host ”   – change UPN from: ” + $_.UserPrincipalName + ” to: ” + $_.PrimarySmtpAddress
   Set-ADUser -Identity $_.DistinguishedName -UserPrincipalName $_.PrimarySmtpAddress
 }

Have a nice day,
