Free/Busy Calendar Access Mode

The Free/Busy Calendar Access Mode is now available for Office 365 Enterprise connections. This allows you to grant more restricted access to your organization’s calendars.

As Free/Busy access is read-only, Cronofy can see whether a user is free or busy at a given time, but cannot see event details and does not have permission to write events directly into the user’s calendar. See this documentation for more information on the Microsoft Graph scopes Cronofy utilizes.

Events can still be created through Cronofy, but instead of being written directly into their calendar, event invites are sent to the customer’s inbox which they can accept. Updates to these created events will also be sent to the user’s inbox. For more detail on how this behaves for developers, see Free/Busy Access.

The steps to connect your organization’s calendar follows a similar authorization flow to the steps found here but you will be provided with a different authorization screen instead where you will need to select Free/Busy:

Then from here you will need to select Microsoft 365:

Once this has been selected you will be taken to the following screen to link your Office 365 tenant:

After selecting Link Office 365 Account you will see a screen similar to this.

To enable Enterprise Connect, log in to your Office 365 tenant as a user with Azure Active Directory Global Administrator access. This is the minimum required level of access to authorise your organizations calendars via Enterprsie Connect.

You’ll see the following screen to approve the necessary permissions for Enterprise Connect:

Once complete, you’ll be redirected back to your software vendor’s application where they’ll synchronise your user’s calendars.
