I have a user who does not receive invites or calendar appointments. If another user send him a invite to a meeting, he does not receive the email assking him to accept, tentative, or decline this appointment. The appointment is automatically scheduled on his calendar. He can, however send out invites and the recipient gets the email notification request to accept or decline invatation. I checked his setting in Outlook and everything appears to be ok. He is using Outlook 2003 in a Microsoft Exchange 2003 environment. I think he is blocking invites. Where would I check to see if this is what going on and how to turn it off.
