Just got an S5 a week ago and the only thing that I cannot get working so far is to have my calendar sync properly to my Microsoft Exchange ActiveSync account which is configured to be my company Outlook365 account. If I create an event within my Outlook365 calendar, it will get pushed to the phone calendar during a sync without a problem. However, if I create an event on my phone calendar, it will never appear on my Outlook 365 calendar after a sync. Any suggestions on what might be causing this would much appreciated.
