Unable to sync Outlook data with Windows Vista and how I solved it.

I came across multiple posts about issues where only files and Favorites would sync with Vista and WMDC but not Contacts, Calendar and Tasks. I experienced the same issue this week-end after installing VistaUltimate. Deleting existing partnerships did not help. My Outlook data did not sync even though my HTC S620 would show up in WMDC and synced my favorites. A hard reset was an option since I had the same data on my Pocket PC, but I was determined to resolve this without hard resetting.

I connected my Eten M500 and it synchronized flawlessly. Same for my wife's HTC S310. With the help of a fresh beer, I went to create a new standard account on my PC. I logged on with the new account and started Outlook 2003 to create a profile. Then I connected my Smartphone. The screen to delete an existing partnership came up since I was already synchronizing with two PCs - My
home and Work PCs. So I deleted the office partnership. WMDC saved my new settings and I named my new connection as Home instead of the default Windows PC3. Amazingly, my device started synchronizing with the PC. I went into Outlook and all my data were there. But I wasn't done
yet since I wanted to sync using my own Vista account.

I logged off and logged back on using my own account. Since Outlook already had data from my Eten, I deleted them all, connected my Smartphone and deleted one existing partnership. After that my device synchronized with the PC. I went into Outlook and they were all there.

Just to verify, I disconnected the phone, added a new contact and appointment and connected again. Confirmed, the issue was resolved.
