I'm sure the answer to this question is all around ~ I just cant find the right way to search for it correctly. Here's what I got:
We use a mail-enabled security group in active directory to e-mail the group AND for access to a file share. This group has a few user accounts which are not mail enabled, but they still need access to the file shares.
In Outlook, when an email is sent to the group, NDR's are sent back because some of the accounts are without mailboxes.
Why? These non-mail-enabled accounts don't appear in the GAL by themselves, so I'm curious why they still appear in the GAL under the group? I peeked around ADSI, but couldnt see a specific setting for this. ShowInAddressBook is clear.
Thanks for your help!
