In the last two weeks the calendar function in WLM2012 has been working strangeky.  Everytime I log into the program I get another copy of the calendar showing up under my hotmail account in the left column.  Even if I delete the calendars, they reappear if I shut down WLM and then start it up again.  Most, but not all entries show up twice.  Most entries, but not all show up on the calendar at outlook.com and on my iPhone.
