My HotSync process has been working fine for years as I've transitioned from a Palm IIXe to a Treo 300 to my current Treo 600. I use it primarily to synchronize my Outlook calendar and address books with my PDA. All of a sudden, however, my Treo calendar is empty. I've tried fiddling with the settings, including forcing the Desktop to overide the Treo, but to no avail. I've also updated PocketMirror from version 3.1.5 to 3.1.7, thinking that might be part of the problem, but it didn't help. Any ideas?
