My calendar has become infected with many duplicate entries, in some
cases, four and five duplicate entries for the same appointment.
Microsoft says these should be deleted entry by entry using the CNTL key
but there must be thousands of them.

Surely there is a more efficient way of eliminating duplicates. Any
suggestions?

Thanks,

DOW
