Scheduling and managing events using Outlook.com calendar
The question has NOT been answered. I, like everyone else posting, cannot sync between my outlook.com account and my Outlook 2013 calendar. I AM USING THE OUTLOOK.COM CALENDAR THAT WAS CREATED WHEN I ADDED THE OUTLOOK.COM ACCOUNT TO OUTLOOK 2013. I can add events to the calendar in Outlook 2013 (the outlook.com active exchange calendar) and they will not appear in outlook.com. I can add events to the outlook.com calendar and they will not appear in the Outlook 2013 calendar.
Just check the forums; many, many people have reported this issue with Outlook 2013.
