I have one user that is reporting that the GWMS web page matches his GroupWise client but nothing is being sent to his Palm Treo. The status log shows this:

10/01/2007 12:32:43 PM - Synchronization started
Connection Info
Connection type: Dialup
Device name: Treo
Sync via: Sync (user initiated)
Encryption: AES
Bytes in/out: 1124/1630 (* actual over the air count may be higher)
Duration: 00:34

There's no mention of mail or contacts or anything being sent out. I've already gone as far as deleting his user and device accounts and recreating them. It lasted about a week and started failing again.

Any suggestions?
