I upgraded to the 8900 about 2 months ago. Since then I have had to change my pc to one operating Vista. The sync doesn't sync my calendar to Windows Calendar...Orange tell me it will to Outlook 2007 - (Which I don't have) Is this the only solution?

What did you use before you moved to Windows Live?

I don't think Windows calendar is supported. I know Outlook 2007 is. Download and install DM 5.0. If Windows calendar is included, it would be using that DM version most likely.

Here is a link from the Microsoft Support Forum concerning this issue.

Blackberry sync for calendar and contacts - Windows Live Help

ALso using the SEARCH function, I found this: Contact syncronization options?

It appears Windows Calendar and Mail are not part of Windows 7 either.
