Not that it helps you - but I ran into this in a server I maintain last week. Also, OWA-originated emails had their "From:" header set to the legacyExchangeDN of the sender, as opposed to the typical displayName.
I rebooted the server. That took care of it. I didn't have time to debug it as too many people were "Screaming". I do presume you mean Exchange 2007 sp1 plus current UR. ________________________________ From: Campbell, Rob [rob_campb...@centraltechnology.net] Sent: Tuesday, May 05, 2009 12:31 PM To: MS-Exchange Admin Issues Subject: System message lost display name I have a puzzle. Exchange 2007 SP2. Last night all the system mailbox cleanup messages came through without the “Microsoft Exchange” display name. All they show is the smtp address in Outlook. I also got reports of messages delivery and read receipt notifications coming in the same way during the same time period. I tried to recreate it and can’t. I even re-ran the mailbox cleanup, and now all the cleanup notification show up normally. Does anybody have any ideas where to start looking for a cause? ************************************************************************************************** Note: The information contained in this message may be privileged and confidential and protected from disclosure.
