Exchange 2010 powershell problem deleting secondary email address

Mark Lewis

We are letting our secondary email address go (old name). I deleted the domain from the policy and accepted domain in Exchange but it left all the old email addresses on the recipients. I really need to know how to remove them form 200+ users in one swoop but decided to test on a single user first.

I ran this command: Set-Mailbox "John Doe" -EmailAddresses @{remove=""}

I got this in return: WARNING: The command completed successfully but no settings of ' Doe' have been modified.

Obviously the secondary email address was not removed.

Try the following script.  Run it in the Exchange Management Shell.  You will need to update the $OUScope variable and "*@d2.local" for your organization.  It will recurse through your AD and remove any proxyAddresses with the specific domain name.

$OUScope = "DC=d2,DC=local"
$N = 0
Write-Host "Searching mailboxes in $OUScope...."
foreach ($Tmailbox in Get-Mailbox -OrganizationalUnit $OUScope -ResultSize Unlimited) 
     $Tmailbox.EmailAddresses | ?{$_.AddressString -like '*@d2.local'} | %{
     Set-Mailbox $Tmailbox -EmailAddresses @{remove=$_}
     Write-host "Removing $_ from $Tmailbox Mailbox"

Can you try to  restart the Transport service or Restart the server and see if the secondary email is gone.

Check the exact email address you wanted to remove. The code shown above will of course take care of that for all users found; your issue with the test case should be solved if you replace Get-Mailbox -OrganizationalUnit $OUScope -ResultSize Unlimited with Get-Mailbox "John Doe" in #a42061724 ( $OUScope doesn't play any role here then, of course). And you can remove the occurences of $N, if you do not need a variable counting the removals made.
