We're have a problem with random users Outlook 2013 crashing using Exchange Activesync. I've isolated the problem down to the calendar file in the users file (AE1279A3_calendarData.xml & AE1279A3_calendarData_bak.xml).  What I found is to fix the crash is to delete or rename the calendar file in the user’s folder on Smartermail server, then remove the account from outlook and then add it back, the problem goes away.  Any thoughts or ideas to resolve without killing the calendar would be approciated
