Office 365 - Changing Default Calendar Permissions

By default, your calendar (or a resource calendar) can be subscribed to and provides free/busy information to all other UW-Milwaukee Office 365 users. To change how your calendar is shared, select your Office 365 client from the list below and follow the instructions for that particular client.

There are four basic permission levels that can be chosen for campus-wide calendaring sharing:

  • Permission level definitions

    • None
      No data is presented. This user will need to contact you to get any information.
      Free/Busy time
      View only start/end date/time
      Free/Busy time, subject, and location
      View only start/end date/time, subject, and location (except for "private" - which only allows free/busy)
      Reviewer
      View full details of all events (except for "private" - which only allows free/busy) - start/end date/time, subject, location, description, attendees, and attachments.



Important: At this time, Outlook clients must be used to modify the global default permissions. Outlook on the web can only modify these permissions at a per-account basis.


Calendar access control using Outlook 2010/2013/2016 (Windows)

After you have configured your Office 365 account in Outlook 2010/2013/2016, you may want to configure your default calendar sharing permissions as well. Note: If you are the owner of a resource and have subscribed to the resource calendar, you can also perform these actions for the resource. Just make sure you have performing these actions as the resource when following these steps.

    calendar properties screen

    The Default permissions level will be "Free/Busy time". When set to this value, this setting allows others to view whether you are free or busy, but does not allow others to see what you are doing during that time, nor with whom you are meeting.

  6. Make sure Default user is selected and use the options within the 'Read' box to change the desired default permissions for your calendar. To fully restrict others from seeing your calendar, set the "Read" permission level to "None". This setting will only restrict them from viewing your availability, they will still be able to invite you to a meeting. If you wish others to have greater access to your calendar, set read permissions to "Full Details" or "Free/Busy time, subject, location".

    Please note the "Permissions" for the Anonymous user. Anonymous users are users who have not yet migrated to Office 365 or who are entirely outside of the University of Wisconsin - Milwaukee system.  If you wish to change calendar viewing permissions for these groups, you will need to change these here. Do not delete this account/user.

  7. When you are done setting your permissions, click on "Apply" and then click on "OK" to exit the Calendar Properties dialog box.
