I made a group in Office 365 and invited my coworkers to join the group. The only function of the group is to serve as a group calendar. I was able to successfully link Outlook 2013 desktop with the Office 365 group calendar. I had no issues for a while until one day a coworker was having sync issues. I tried to fix it, but was not successful. The calendar now displays all the members individually instead of as a normal calendar.

The question is, how do I get the calendar to display and sync correctly?

Hi,

Please confirm whether other users can view this group calendar in Outlook. Additionally, is the group calendar a distribution group calendar or a group calendar created in Outlook?

If it is a distribution group calendar issue for a specific user, please remove this opened calendar and create a new profile in Outlook, add this group calendar back to have a try.

Regards,

Every other user can successfully view and edit calendar from Outlook. Only me and one other use are experiencing this issue.

How do I know if it is a distribution group?

I made the group via the Office 365 online interface. I then invited users to the group and individually opened the group calendar from their Outlook.
