Powershell: Change UPN on list of users
I needed a script to bulk change a list of users to a new UPN i came up with this.
# $Users = gc c:\temp\users.txt | get-ADUser foreach ($User in $Users) $UserUPN = $User.UserPrincipalname $UserUPNwithOutDomain = ([regex]::matches($UserUPN, "([^@]+)")).value[0] Set-ADUser $User -userprincipalname "$UserUPNwithOutDomain@microsoft.com" }
# $Users = gc c:\temp\users.txt | get-ADUser foreach ($User in $Users) $UserUPN = $User.UserPrincipalname $UserUPNwithOutDomain = ([regex]::matches($UserUPN, "([^@]+)")).value[0] Set-ADUser $User -userprincipalname "$UserUPNwithOutDomain@microsoft.com" }
