List all mailboxes that forward to a specific user

I have this script that lists all mailboxes that are forwarding email, however, I am curious if there would be a way to make it return all mailboxes that forward to a specific user. Basically I'm trying to find out every mailbox that forwards mail to "johndoe". Any help would be greatly appreciated! This is for exchange 2007 btw...

Here's the script so far:

$fwds = get-mailbox | Where-Object { $_.ForwardingAddress -ne $null } | select Name, ForwardingAddress

foreach ($fwd in $fwds) {$fwd | add-member -membertype noteproperty -name “ContactAddress” -value (get-contact $fwd.ForwardingAddress).WindowsEmailAddress}

$fwds

Solution

  • Exchange uses CanonicalName for the forwarding address, so you'll need to look that up from the user name. Since it could be a Mailbox, DL, or Contact, the easiest way I know of is to use Get-Recipient, and grab the Identity property.

    $RecipientCN = (get-recipient johndoe).Identity
get-mailbox | Where-Object { $_.ForwardingAddress -eq $RecipientCN }
