4. Click on the Refresh button.
   
   
   
5. A web browser session will be launched. Enter the Dropbox login credentials.
   
   
   
6. Copy the authorization code for Dropbox.
   
   
   
7. Paste the authorization code back to AhsayOBM/AhsayACB and click OK .
   
   
   
8. After the authorization code has been verified. Click OK to continue.
   
   
   
9. Click Save to update the backup set.
