Windows Phone Thoughts: Windows Mobile 2003 IMAP Woes - Anyone Else Have This Headache?

Every morning, I wake up and pick up my iPAQ 4150. I turn it on and, using WiFi, pull down my Pocket PC Thoughts email messages using Pocket Inbox and my IMAP account. I'll read, delete, and move messages to different sub-folders. I'll usually do several send/receives during this time. Usually, it will only download new messages, and by all appearances it will look like everything is OK. However, more often than not (I'd say 80% of the time), I'll sit down at my main PC, fire up Outlook 2003, and it will download all the messages that I'd already processed - and they won't even be marked as read. Sometimes this behaviour will happen on the Pocket PC - messages will be downloaded even though I just deleted them. This cycle can continue several times - I delete messages, do another send/receive, and all those deleted messages are downloaded and marked as unread. It's worth noting that I see the same problems in all the email accounts I have on the server (PPCT, SPT, DMT), but not when checking my two IMAP accounts on Exchange servers.

This behaviour happens with "Empty Deleted Items" set to IMMEDIATELY and ON CONNECT/DISCONNECT. This setting seems to have no impact. Sometimes I'll do a TOOLS > EMPTY DELETED ITEMS, but that has no effect on the problem either. Our server is running Linux Redhat 7.3, and the IMAP server is UW IMAP 2001a. This is a very popular mail server, so if I'm having this problem, I have to think others are too.

Vote in the poll and give me your feedback if you've ever seen similar issues - or, better yet, know what the solution is, because it's driving me insane. :evil:
