Nikki, I have the same problem but with Outlook 2007, used with Vista and
Exchange 2007 in Cached Mode. It started about a week ago and as far as I
know I didn't do anything to cause it.

If I try to create a Calendar item when Outlook is online, the new item
always disappears and I get this error message:

Could not save item. The connection to Microsoft Exchange is
unavailable.
Outlook must be online or connected to complete this action.

The only way I can create a new Calendar item is to go Offline, create the
item, then go back online.

I also can't create a Task or Contact while online. Email works fine.

I tried the fix process you described here (clearing the forms cache and
deleting Frmcache.dat) then restarting my PC, but to no effect.

Do you have any suggestions? I'm surprised that I can't find any
references
to this problem on the web for Outlook 2007.

Thanks,
Garland
