Resolved Meeting Requests goes straight to the Deleted Items Folder

I have a user that is using Outlook 2003 and we use Exchange 2007. When she receives a meeting request, it goes to her Inbox for a couple of seconds, then goes to her Deleted Items folder. She has no rules setup and I also verified that the under Tools>Options>Calendar Options>Resource Scheduling..., the Automatically accept meeting requests and process cancellations check box was unchecked. I also verified that under Tools>Options>E-mail Options>Tracking Options..., the After processing, move receipts to check box was unchecked. These were two possible solutions that I googled. I rebuilt her mail profile, but none of these worked. does anyone have any suggestions.

 

Yes, she is on SP3.
