I'd like to exclude a single email address or recipient from an existing dynamic distribution group in Exchange 2010. The group is the generic "Everyone" group, and I'm interested in excluding the dedicated domain account used for our external mail journaling software (MailArchiva). I've seen references online to filtering on a custom attribute, but I'm seeking a solution that will allow something like:
Everyone = all Exchange mailboxes EXCEPT for 'Journal User'
It's a basic request, but the Exchange Management Console only seems to allow inclusions in its filters. Perhaps this is attainable via the Powershell.
