Google calendar sync is not ready for primetime

So, after a few weeks of experimentation, I finally am happy with my Gmail setup and I was ready to completely migrate my Outlook content to Gmail. I moved my address book, and I downloaded the Google calendar sync tool.

I still need to keep my Outlook around until I find a way to sync my WM6 smartphone with the Google calendar/Address book.

Everything worked fine. However, in the middle of the day, my entire Google calendar was obliterated. Every single item gone. After investigation, I was able to tell that the Google calendar sync tool was getting errors trying to access the calendar in Outlook (through MAPI) and interpreted this as me having removed my items from the calendar.

I was able to retrieve my calendar from my smartphone. Everything was not lost. But the Google calendar sync was promptly uninstalled. I guess I am waiting for their next version.
