Description

This Know How articles provides instructions on how to re-authenticate the Microsoft 365 backup set when the AhsayCBS is upgraded to version 9 or above.

Solution

After upgrading to AhsayCBS v9 or above, Microsoft 365 backup settings of existing backup sets must be updated. This will ensure that moving forward there will be no backup and restore issues to be encountered once Microsoft implements its product roadmap for Modern Authentication. This only needs to be done once per backup set.

  1. Log out all Microsoft 365 accounts on the default browser before starting the update of backup set.
  2. Log in to the user web console.

    For instructions on how to do this please refer to the Login section of the AhsayCBS Guide.

  3. Click the User icon on the user web console.
