Hey all - this is my first post. I am a big Treo fan having owned the 600, 650, 750w and now the Pro.

This is my first time experiencing such a problem.

As I have done for a while, I use the WMDC to sync Outlook 2007 (on Vista 64 bit) to my PDA. Generally, I have no problems.

Recently a new problem has developped.

Randomly (I cannot seem to pinpoint what causes it) the partnership will get screwed up so that items created on Outlook (PC) do not sync to the PDA. Like if I create a new Calendar item or Contact, as soon as it is created, I will see the little Icon spinning in the system tray however, the new item will not appear on my PDA.

I've tried unplugging and reconnecting the Sync cable and also closing and reopening Outlook -- even resetting my PDA and restarting the computer. Somewhere in between these acts the problem will be solved however anything which was created on the PC, while the problem occured will still not sync (although new items will sync again once the problem is solved). Additionall, if I go to the items which appear only on my PC and chance something (i.e. add a note, move it forward an hour, add a phone number to a contact etc. it will then properly sync).

As you can imagine this is a huge problem. Like it's late at night and I need to do a few things tomorrow and fit them in between another bunch of items already existing. So I type it into my PC and sync and go to bed. The next day, as I'm going through the day, it doesn't occur to me that some items didn't get synced and I only discover it when I get home later that night that it's in my overdue. (Or even worse, I add crucial notes to an existing appointment; I get to the appointment, whip out my PDA, and check my notes field and it's just not there).

The way around this is, when I discover it happening and I cannot say for sure how many items I have added since the problem began, is I delete the parnership and reconnect my PDA. Everything gets deleted from my PDA and then I set up a new partnership and everything gets brought back from scratch. Net time to do this, about 10 minutes - not what I want to be doing on a daily basis (which is roughly how often this problem has been happening lately).

I have tried checking and unchecking the "advanced network connection" box and it doesn't make a difference.

Does anybody know what this problem is, why it is happening, and what solutions will permanently stop it from occurring.

Thanks
