Outlook 2007 - Can not update calender

[Maloneous]

My Outlook has developed a problem with updating new information. (For
Example: If I try to enter a new appointment in the calender I will get an
error message indicating that Outlook could not complete the request, or that
the appiontment conflicts with another appointment, even though it doesn't.)

I have downloaded and installed all Microsoft Updates and Service Packs, yet
the problem still exists. I have run Office 2007 Diagnostics and still the
problem exists.

Any suggestions?

did you try resetting the view?
