Just to drill down a little more, do you have windows desktop search enabled
on the Vista and not on the XP? I'm researching similar issues at the
moment.

Dear Anyone,

I have recently installed Vista Business and Office 2007 on my development
workstation. It's working quite well, except i have a critical problem
with Outlook 2007.

Whenever i try to access anything to do with the calendar, it hangs. The
processor goes to 25% (one of the four cores maxed) and that's it. Game
over.

I'm connecting to an Exchange server, and everything works fine in XP with
Office 2007 on a separate partition. Also, no problems with accessing the
calendar using Outlook Web Access.

Any ideas?

TIA
