For testing purposes; In an effort to forward emails to an external email address, I followed the following thread.
After creating the new contact and confirming the forwards worked, I deleted the contact but left the user. The user's email address works and no problems sending and receiving emails. But, Now the user does not show up in GAL nor has the "Email Addresses" tab under the users properties.
Under the "Exchange Advanced" tab the "Hide from exchange address list" is unchecked.
and I rebuilt the "Offline Address List" in Exchange System Manager.
