Configuring Office 365 Mailbox Access

In order for Folder Permissions Manager to access the mailboxes hosted in Exchange Online, it is necessary to configure an Entra ID registered app with the appropriate permissions (to update mailboxes) and a certificate (for authentication). Clicking the Configure button in the Office 365 Mailbox Access group of the Environment Configuration dialog launches the Configure Office 365 Mailbox Access Wizard that will guide you through the process of configuring this app; the wizard can either register a new app or ensure that an existing app is up-to-date.

Note There can be a delay between completing the wizard and the configuration being applied. You can always use the Configure button to re-run the Wizard if required.

Once the registered app has been successfully configured, it is recommended to click the Test Connectivity... button to test the mailboxes in your Exchange Online tenant can be accessed as expected.

At any time, you can login to the Azure portal (as a Cloud Application Administrator) and navigate to the App registrations blade to review, modify or delete the Folder Permissions Manager Application.
