We have Exchange 2003 running on Windows 2003 server.
I was asked to resolve an issue where some messages addressed to one recipient (internal) are not delivered as they are supposed to. User stated that it happened a couple of times when he received messages at 2PM that are dated 8 something am. Some of the messages were addressed to him from other internal users from our organization and one or two messages were from external sources. User didn't give me any detailed info on sender, subject line etc. So, I couldn't really check in Exchange Message tracker. I did restart Exchange services and also did check that the mailbox is within it`s limit as well as checked the queues, nothing unusual.
What else should I check for ? Did anyone else had this same issue ?
I didn't hear any complaints from anyone else about the same issue.
