You cannot open a shared calendar in Outlook for Mac

Applies to: Outlook 2016 for MacOutlook for Mac for Office 365


When you have access to multiple shared Calendar folders, you cannot open one or more of the shared Calendar folders in Microsoft Outlook 2016 for Mac or Outlook for Mac 2011.


In Outlook 2016 for Mac and Outlook for Mac 2011, you cannot open a shared Calendar folder that is not a sub-calendar of the user's shared default Calendar folder.

For example, a user shares the following Calendar folders with you: 
  • Calendar
  • Second Calendar
  • Third Calendar

Third Calendar Snapshot

In this example, the "Second Calendar" folder is a sub-calendar of the user's shared default "Calendar" folder. Therefore, you can open the "Second Calendar" folder in Outlook for Mac. However, the "Third Calendar" folder is not a sub-calendar under the default "Calendar" folder. Therefore, you cannot open this folder in Outlook for Mac.


To resolve this issue, have the calendar owner create all shared calendars under the default "Calendar" folder.
