Hi guys, trying to remove a lists of users from different domain that have secondary email address contain the word "_site" is that possible with powershell? Thanks

get-mailbox | where {$_.emailaddresses.proxyaddressstring -like "*_site*"} | foreach {
$email = get-mailbox $_
$emailremoval = $email.emailaddress | where {$_.proxyaddressstring -like "*_site*"}
$email.emailaddresses -= $emailremoval
set-mailbox $email -emailaddresses $emailremoval
}

something like this should work, please test it before applying it across your environment.

Thanks
Pres

Hi Pres,

sorry to say that the script that you provided is not able to work, it does not remove the secondary email address of the users.
