I  have recently upgraded from Vista Home premium to Windows 7. In the process, lost windows calendar. (I guess it's no longer available).

Started using Windows Live mail Calendar. On the desktop - no problem, although apparently I can't save nor export any of the calendars I have created on the desktop. When I open Windows Live mail on my laptop, all of the calendars I have created on the desktop are there, however, not all of the appointments/events are there. I would like the two calendars to be identical. Is there a way to do this?

By the way the calendars are linked via my Yahoo email account and I do have a Microsoft account.
