    How to remove Email Address with .net suffix. Via AD PowerShell, Exchange Management Shell or Quest Shell.

    An AD property or an actual Exchange email address domain? (Where the domain is *.net)

    If it’s the 2nd one, why would you need a CSV? you can simply spool through your entire list of users and use this PS script.

    foreach($i in Get-Mailbox -ResultSize Unlimited) {
      $i.EmailAddresses |
        ?{$_.AddressString -like '*@yourdomain.net'} | %{
          Set-Mailbox $i -EmailAddresses @{remove=$_}

    This will remove entries that has *@yourdomain.net from all mailboxes while leaving all other email addresses intact, perfect for situations where a certain OU had two domain suffixes and one was decommissioned.
