My calendar is has been sent to sync with Exchange server and I have already have an existing  exchange account. I did have it sync with my calendar on my computer after some phones issues and and having to replace the computer chip I set back up exchange  It says that it has synced to the calendar on my computer. However the calendar on my phone is still empty and does not have any of the dates that are on the computer calendar. I have a Samsung Galaxy S3  version is 4.4.2

What does your e-mail administrator say?

Hi,

I understand you can sync successfully the calendar on your computer, but you dont update the calendar on your phone.

I suggest you can try to reconfigure your account on your phone.  Please refer to the official document to configure:

if it doesnt work, I suggest we can ask question in Microsoft Exchange activesync  forum to get an more appropriate answer: https://social.technet.microsoft.com/Forums/exchange/en-US/home?forum=exchangesvrmobilitylegacy   

Thank you for your understanding.

Best Regards,
