What should I do if access_denied / AADSTS65004 appears when approving Patisco Mail in V5?

1. Confirm that approval has not been completed. access_denied / AADSTS65004 indicates that consent was not given during this authorization attempt. 2. Switch to an account with the "Global Administrator", "Cloud Application Administrator", or "Application Administrator" role. 3. Open the approval link again and complete approval using the administrator account.
