Has anyone else seen this problem?

I file a message into a MS Outlook inbox subfolder on EITHER the desktop or the bb. The message will be in the desired folder UNTIL I wirelessly sync my bb, at which point the message leaves the folder under which it was filed and goes into Deleted Items. Only AFTER connected my bb via the USB cable does the email leave Deleted Items and return to the right folder.

I am using Windows XP, 8700c and wireless sync is on for emails, off for address book. Running 4.2.0.10 Desktop Manager and 4.1.0.284 on the 8700c.
