Sometimes i visit customers together with my team members but they forget to add me to the required atteendees so it is the meeting is appearing in my Outlook Calendar.
If i enter the meeting and add myself to the meeting (or they do it), still it is not appearing in my calendar. It looks like the once the invitations have been sent (or the meeting has been created), there is no way to add any required attendee other than canceling the meeting and creating a completely new one.
