Ever since uninstalling windows live local for outlook I cannot create an
appointment from within the calendar (even reinstalled the app - no luck).
The only way I can perform such a task is to find a contact and choose to
schedule a meeting.

The error I recieve is "The form required to view this message cannot be
displayed. Contact your administrator."

I have cleared the form cache and tried adding Microsoft's IPM.Appointment
form as I would a custom one....still no luck. Any suggestions? Quite an
aggravating little bug.
