I have a user that every time she opens up outlook she gets 60 or so "Not Read" message receipts. She had this issue before when she was clearing out her mailbox, but we corrected it by disabling the Read receipts options in outlook. However this option is still disabled, and now we can't figure out where these messages are coming from and how to get rid of them... She's connected to an exchange server, and based on the tinkering I've done on the user's computer, it seems to me like the messages are coming from the exchange server... Problem is, I can't figure out where they are and how to stop them from filling up her inbox every time she opens outlook.
Running Outlook 2000, exchange 2003
