4. Under the Allow column, click to select the View information store status check box, if this check box is not already selected.
5. Click to clear the check boxes for any permissions that are not required, and then click OK.Note You may have to follow this step if you clicked Add to add the account in step 3. This is because every check box in the Allow column was selected when you added the account in step 3.
