Currently, I schedule/track the vacation time of my office members in an
Excell SpreadSheet; however, it obviously does not update thier status like
an an appoinment in Outlook. Thus, I would like to make an Outlook calendar
to track it.

Is it possible for me to "schedule" folks' vacation (say, like an
appoinment) in a single calendar and have it update the availability status
in their outlook (without scheduling me for the same vacay)? ...and how would
I go about it?

Thanks a lot!
