User hs suddenly lost the option to "send only to added/deleted"
attendees. Literally was working on Monday, then not working on
Tuesday. Exchange 2003 environment, specific user is using Outlook
2000. When a new attendee is added to a meeting, the option to send
only to updated users is not given, just the pop-up to send updates to
attendees, which sends to everyone on the list. Any ideas would be
greatly appreciated.
