Treo 750 - Outlook Mobile - Sending duplicate emails every time with ActiveSync

We have a handful of Windows Mobile devices connecting to an Exchange 2007 server via ActiveSync. I have one of these devices, a Treo 700, and it has been working fine. A coworker was setup on a Cingular Treo 750 and his initially worked fine but all of a sudden after a few days now every time he sends an email from his windows mobile device via Outlook Mobile the receiver gets 2 copies of the original message back to back. I soft reset the device, checked there was nothing in the outbox, everything seems clear... The only way he is 'synching' is wirelessly with activesync.

I've seen people claim to have the same problem using other types of accounts besides exchange/outlook and they claim that hard-resetting it would work for a while but the problem just comes back after a while. I haven't gone the hard reset route because I don't want to waste my or his time, I'd rather know *why* it might be happening and start from there.

Does it only happen if he is synced while sending the email? If so that may causing it.

No, he never physically syncs the device via USB, Bluetooth, IR, or any other method- the only "Syncing" is wirelessly over activesync and that is done automatically/in real time.

It does not sound like a issue with the exchange is it happening for him in his internal email? If not then I would look towards the device and hard reseting it. Also is there something wrong with the account settings on the device I had a user setup 2 mailboxes and something along those lines was happening

So he syncs through an internet connection? What may be happening is that the outlook he is syncing with is sending the second email. Does it happen the other way, when he writes an email from the workstation he is syncing with does it send duplicates?

No duplicates when sending an email from his workstation, on when sending from his PDA... I'm guessing a hardreset will work, but he didn't make any changes since it's been configured so I'm guessing whatever caused this to become a problem will just happen again.

Try disabling activesync and then sending an email. I'd try that before I hard reset.

I diabled activesync and then could not re-create the account correctly again... it would fail every time it tried to sync the contacts from that point on.

I ended up doing a hard-reset and everything synched fine but of course the email is still have the same problem- send 1 and the receiver gets 2.

I would say something is wrong with the device if there are no issues with the workstation then the device is more then likley the issue. One thing you can try is attaching the device to another email account to see if it has the same problem

Well the user is going away for the rest of the week... He'll deal with the double emails for now... when he gets back I'll upgrade it to Windows Mobile 6 and see if that solves it.

Also in the checking, I noticed that sure enough there are 2 copies of each item he sent in the sent items, so exchange thinks it's receiving 2 copies.

I am curious about setting it up as a different user, I may try it right before I upgrade just to see what happens.

Well it's been several weeks since we upgraded the user to Windows Mobile 6 and the problem hasn't reoccurred.  Still don't know why it started to begin with.
