After setting up your Microsoft 365 admin account, you can activate a backup task for Exchange Online as follows:

  1. In the CAB Management Portal, click Backups in the sidebar menu.

    The list of backup tasks opens.

    • If you do not have any backup task added yet, select Office 365 Exchange.

    • If you already have some backup tasks set up and configured, click Add Backup Task on the upper right, and then select Office 365 Exchange.

    The authentication dialog box opens.

  2. In the authentication dialog box:

    1. In the Backup Name box, enter a name for the backup task.

      This name is used to identify the backup task in the reports and notifications. You can change it later.

    2. Select the preferred authorization type.

      Note

      Since Microsoft will soon deprecate the credentials-based authorization for their Microsoft 365 services, we do not recommend using it, and thus it is not available by default. For Exchange backup tasks, only the OAuth-based authorization is available.
    3. Click Authenticate to go to the Microsoft 365 sign-in page, and complete authorization.

      Once you complete authorization, you will be redirected to the backup task page again.

After you activate the backup task, continue with configuring backup task settings and managing backups for user accounts.
