take control of calender for user that does not exist.
 

Greetings,
this is my first post ever...there is a user that is no longer with my
company and he shared his calendar to the sales department and has a
recurring event that cant be deleted. Now to put it in perspective we have
recently switched from exchange 2003 to 2008 and this user was never added to
the 2008 server and the 2003 server has been turned off and even though the
user was never switched to the 2008 server for some reason his calendar still
shows up and i cant delete it. And i don’t have a profile for him that i can
delete or make changes too. Please help!!!
