Ways to sync outlook calendar?
Try to use Add to Cal module. I hope this module solve your query.


  A field formatter providing a widget for exporting events to:
  
  
  Google Calendar
  Yahoo! Calendar
  iCal
  Outlook
  
  
  The field formatter provides a button next to the field that shows a drop-down menu. This
  menu contains links to the supported formats, and includes basic
  styling that can be easily modified through CSS.
