Question : User can't change anything in his own calendar in Outlook 2003..

Hi,
Until today we were able to adjust times and add new entries to his calendar, but for some reason it will not allow us anymore.  Nothing has changed with permissions either.  When you double-click on an item in the calendar it looks like it is going to load, but within .5 of a second it doesn't do anything.  Any ideas??  Thanks

Check that SP3 is installed:

Then try running the following command line switch.
With Outlook Closed:
Start>Run>Outlook.exe /cleanprofile

If no good then might need to run ScanPst
