Exchange 2003 Is Confused

A couple of strange things are happening…

A user is getting an Over Limit message but she is NOT over limit. The message even notes that she’s using 58mb and her limit is 100mb, but it still generates the over limit message.

Also, two users who have been removed from all distribution lists still generate bounce messages when a message is addressed to the list that includes everyone.

I’ve stopped and restarted the message store and have confirmed that the two users generating bounces are not members of ANY group.

What else can I try?
