Exchange server 2003 - We recently deleted a user who had shared rights to another user's calendar. Now everytime the existing user sends out a calendar invite which gets replied to the user replying gets a bounce message about the user that we deleted. We've looked all through the existing user's calendar share and cannot find any reference to the deleted user. How can we clear this up?
