Outlook Calendar Connection

Garmin Connect has an option to connect it's calendar to Outlook and Office 365 Calendar which I find very useful. However, when I try to connect to my Office 365 account an error message pops up with the following message: "Sorry! The calendar feature is not supported for this Office 365 account". Has anyone tried this with their 365 account and experienced the same problem, perhaps found a solution to it, or is it working for you?
