I have been using Outlook for years and years now. I would like to
clean up my appointments - there has to be at least 8 years or more
of appointments.

Display your calendar in a table view and sort by end date. Your old
appointments will be very evident. You can use left-click, Shift-left-click
and CTRL-left-click (as in most Windows applications) to select multiple
entries or ranges of entries and then click Delete or, if you want to save
them, you can use AutoArchive or manual archive to copy them to another PST.
