There's a user who is able to send/receive and accept/reject meeting invites on the domain. However, when someone outside the domain tries to send him invitations, they never reach his inbox/calendar in the mail.app for macs and OWA. Everyone else is able to receive external invitations. The sender is not receiving "undeliverable errors" and message tracking in Exchange tools shows that the email is being delivered. Has anyone seen this before? Is there a setting on the server that is being over looked.
