If you are looking to regrant access to an Office 365 organisation, you can follow the steps below:

1. Go to the 365 Total Backup Dashboard in Incognito/Private mode 
    
2. Next, go to [Microsoft 365 Organizations] 
    
3. Click on the 3 dots on the right-hand side and select [Re-grant Access]
   
   
   
    

4. In order to proceed, you need to follow the on-screen instructions in order to grant permission to three applications. Firstly, you will be granting access to Hornetsecutity to be able to revoke access should you wish to stop backing up this organization, then you will grant Hornetsecurity temporary access to create a new application within your organization and you will grant access to the new Hornetsecurity applications to be able to backup your Office365 data.
   
   Finally, if you previously had a previously added tenant and you are re-granting access, you will notice a 4th step in order to allow Hornetsecurity to backup Teams Chats. Note: You might not get this option if access to Teams Chats was already granted previously.

    

   Start by clicking on [Step 1]
   
   
   
   
    

5. You'll be taken to Microsoft's website to log in using your Office 365 Administrator account in order to regrant access for O365 Backup to the account
   
   
   
    
6. Once you've signed in, simply click on [Accept] to proceed. Once you accept, simply click [Close] in order to proceed with the onboarding process.
   
   
   
    
7. As you can see, Step 1 is now marked as complete and you can proceed with Steps 2, 3, and 4 (if access to Teams Chats was already granted, you might not have this step) in order to finish the grant access onboarding process:
   
   
   
    
8. Once all steps have been completed, click [OK]. You have just regranted access to your Office 365 organization.
