Second Time - "Synchronization cannot be completed successfully" message
About two months after I started using the Treo 700w, I was ActiveSyncing my Treo 700w with one of the two PC's I sync the Treo 700w with, and received the "Synchronization cannot be completed successfully" message. After about two hours on the phone with Palm Tech Support, the only remaining solution was a hard reset. The hard reset did solve the problem, but of course, it takes about 2 to 3 hours to reinstall everything. I wasn't too upset because I wanted to do a fresh install of the latest upgrades for all my third party applications. However, I was also determined I would not be doing this again in the near future unless it was because of a system upgrade patch from Palm. Instead of waiting for the free Sprite Backup app to be made available by Palm, I purchased the Sprite Backup directly. I am certainly glad I did.
Two weeks later, I was ActiveSycing with my PC, and again received the "Synchronization cannot be completed successfully" message. I was surprised, and disappointed. Surprised because I had not changed much on the Treo 700w since I reinstalled all the applications after the hard reset two weeks earlier. I was disappointed because there was evidently a serious bug that needed to be fixed quickly by Palm. A search of the web revealed that this problem is not uncommon, and a plethora of suggested fixes have been posted. Unfortunately for me, none of the suggested solutions, including deleting all zero byte temp files, fixed my problem. I did not bother calling Palm Tech Support because I tried everything they had me try the first time I received the message. Fortunately, this time it only took 15 minutes to hard reset the Treo 700w, and do a full restore from Sprite Backup which worked flawlessly. I will ensure I do a new backup each time I add an application.
All my other Windows Mobile devices, including the Dell Axim x51v, another Windows Mobile 5 device, still ActiveSynced perfectly after I received the "Synchronization cannot be completed successfully" message with the Treo 700w. Since all my other devices still worked fine, the problem must be with the Treo 700w, and its interaction with ActiveSync. This is a major problem that has cost many hours of work by Treo 700w users judging by the web posts. A quick solution for this major problem is definitely needed from Palm, sooner rather than later. In the interim, purchase a Windows Mobile 5 compatible backup program and backup your Treo 700w frequently. You will be glad you did when you can cure the "Synchronization cannot be completed successfully" problem in 10 to 15 minutes, rather than 3 hours plus.
