What should I do if access_denied and AADSTS65004 appear when approving Patisco Mail in V5?

1. On the "Approve Patisco Mail" page, confirm that approval was not completed and that the error is access_denied with Microsoft code AADSTS65004, indicating that the user declined permission. 2. Switch to an account with the "Global Administrator", "Cloud Application Administrator", or "Application Administrator" role. 3. Reopen the original approval link and complete the approval process.
