sync calendar in Microsoft outlook and outlook.com

the calendar on my Microsoft Outlook syncs with my iPhone and iPad, but it does NOT sync with the Outlook calendar on my Surface and it does not sync with Outlook.com.

Can you help me sync it with the Surface and Outlook.com?

Also, is there a way to sync the calendar with OneDrive?

Please note, by contacts and emails sync in outlook.com without problem.
