In our office we have an Exchange 2003 server, and clients using Outlook 2010.
Every time user A receives an e-mail, it gets automatically cc-ed to user B. (Note: this rule is applied regardless of whether A is logged on.) I have used MFCMAPI on the server to delete all messages in user A's Inbox's Associated Contents Table of class IPM.Rule.Message, and now when user A uses Outlook, she cannot see any rules. However, the messages are still being auto-cced.
(Some background information: It's very likely that a rule used to exist for this purpose, as this behaviour used to be desirable. User A is the only user whose messages are auto-cced to user B, and user B is the only user who gets user A's mail auto-cced.)
Can anyone suggest why this might be happening and how to fix it, short of creating a new mailbox for user A?
