I use my calendar as a self reminder system.  I have used it in this manner
for 3+ years.  As of mid day last Friday, Outlook woudl not allow me to save
any new appointments.  When I double click the calendar to open a new
appointment, it does nothing.  If I look at the particular day on the
calendar an type in a line, I get an error message that says"Can not save
item".  There is no other indication thta something is wrong, it just stopped
working on me.  Anyone have any ideas on what could be wrong?
