Answer 1

Hi,

Here's a sample code to accomplish the task in Powershell:

$LocalUsers = Get-ADUser -Filter {UserPrincipalName -like '*internal.local'} -Properties userPrincipalName -ResultSetSize $null
 
$LocalUsers | foreach {$newUpn = $_.UserPrincipalName.Replace("internal.local","external.com"); $_ | Set-ADUser -UserPrincipalName $newUpn}

#Get a list of the UPN suffixes

Get-ADForest | Format-List UPNSuffixes

 #Let’s add the UPN suffix

Get-ADForest | Set-ADForest -UPNSuffixes @{add="abc.xy"}

 #Get a list of the UPN suffixes

Get-ADForest | Format-List UPNSuffixes

 #List of all the AD Users in the organization

Get-ADUser -Filter * | Sort-Object Name | Format-Table Name, UserPrincipalName

 #Change the UPN for all the AD users in the organization

$LocalUsers = Get-ADUser -Filter {UserPrincipalName -like '*abc.local'} -Properties UserPrincipalName -ResultSetSize $null

$LocalUsers | foreach {$newUpn = $_.UserPrincipalName.Replace("abc.local","tomrocks.ch"); $_ | Set-ADUser -UserPrincipalName $newUpn}

 #Confirm that the UPN has been changed

Get-ADUser -Filter * | Sort-Object Name | Format-Table Name, UserPrincipalName
