To work around this problem, open directly into the shared calendar.

You can use the following URL to open the user's calendar:

https://yourdomain/owa/user@yourdomain.com/?cmd=contents&module=calendar

  • If no, see Additional help.

In the invitation, notice whether Microsoft Exchange appears before the shared calendar name, as in the following screenshot.

Workaround for opening shared calendar on Mobile/Tablet devices

If you are using Outlook App on mobile or tablet devices, such as Windows Phone, iPhone, iPad, Android Phones, you cannot see other user's calendars on these devices as they only sync your own calendars. The workaround is that you need to use Outlook on the web or Outlook Web App to view the shared calendar, or view it when on a Desktop Outlook for Windows or Mac client.

To use Outlook on the web or Outlook Web App to open the shared calendar from an invitation, sign in with your exchange or office 365 account, you will see the share invitation like this:

Screenshot of a shared calendar invitation in Outlook Web App.

Select Accept to open the shared calendar, and then you will see the shared calendar listed on the left pane under Other Calendars and the events on this calendar on the right pane.

You don't have permission to view a shared calendar in Outlook 2016 for Mac or Outlook for Mac 2011

When you try to open a shared Calendar folder in Microsoft Outlook 2016 for Mac or Outlook for Mac 2011, you receive the following error message even though you were granted permission to the folder:

Outlook cannot open the folder. You do not have permission to open this folder. Contact<Calendar owner's name> for permission.

This issue occurs because the owner of the folder that you want to access shares the sub calendar folder with you but does not share their default (primary) Calendar folder. To fix this issue, the calendar owner must share both the primary and the secondary Calendar folders with you. For more information, see "You do not have permission" error message when you try to open a shared Calendar folder in Outlook for Mac.

Did this solve your problem?

  • If yes, see Additional resources.
  • If no, see Additional help.

You get blank calendar or permission error on Mac even if you have free/busy permission in Outlook 2016 for Mac or Outlook for Mac 2011

A user grants you Free/Busy permission to their calendar, but when you try to open that user's calendar in Microsoft Outlook 2016 for Mac or Outlook for Mac 2011, you receive the following error message:

Outlook cannot open the folder. You do not have permission to open this folder. Contact <user_name> for permission.

This issue occurred because the Free/Busy feature is only available in Outlook 2010 and Outlook 2013 for Windows. To open a shared calendar in Outlook for Mac, the user must grant you permissions of Reviewer or higher. Or, you can view the user's Free/Busy information by creating a new meeting request and then adding that user in the Scheduling Assistant. For more information, see User with Free/Busy permission can't open another calendar in Outlook for Mac.

Can't open one or more of the shared Calendar folders in 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 subcalendar of the user's shared default Calendar folder.

  • Calendar

  • Second Calendar

  • Third Calendar

    Screenshot that shows the Third calendar tab selected.

In this example, the Second Calendar folder is a subcalendar 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 subcalendar 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.
