Calendar items are not visible for a shared calendar in Outlook

In Microsoft Office 365 dedicated, calendar items are visible when you open a shared calendar in Microsoft Outlook Web App (OWA). However, these calendar items are not visible for the shared calendar when you perform the following actions:

  • You use Microsoft Office Outlook to view Free/Busy data for the shared calendar.
  • You use Outlook to open the shared calendar.

Note You have limited Free/Busy permissions for the shared calendar.


This behavior is by design. When the Read permissions level for the shared calendar is set to Free/Busy time or Free/Busy time, subject, location, Outlook does not display an item that is marked as Free.


To resolve this issue, set the Read permissions for the shared calendar to Full Details. For an example of Read permissions information, see the information in the following screen shot:

Click on Calendar 

Click on Calendar Permission

Select on Full Details 

Click Apply and OK
