Question : How do I cancel an Outlook event for an AD user that no longer exists?

There is a recurring event which is scheduled in Outlook by a user who is no longer employed with our company. How can I go about taking control of the event and sending out a cancellation to everybody that has the event on their calendar?

Thanks in advance.

Save yourself time and nerves and do a fresh install once
more.Format everything (backup what you need first) and
install once more.believe me it takes much less time
than troubleshooting your viral infection which even if
'fixed' may produce unexpected results.
So for your peace of mind,do a fresh start and stay away from
pirated software (and say no to drugs :-)  )...
Also get yourself a decent antivirus and not something like AVG...
Get Norton or Kaspersky.
