I have a problem with Microsoft Project adding it's own calendar version (many of them) to my project files. I am not sure why. I delete them in organizer but they must still reside somewhere as they keep coming back.
Listed under Tools -> Organizer -> Calendars
ie): Sample Calendar <- this is my original
Sample Calendar1
Sample Calendar2
Sameple Calendar3
etc, etc, etc.
