Proofpoint Essentials and Azure AD registration
The instructions found on their website for setting up Proofpoint Essentials and connecting to Azure needs updating. Microsoft no longer allows users to access the “App Registration (legacy)” in order to get a KEY without a special character that isn’t supported by Proofpoint. You may have to generate dozens of keys to get one that Proofpoint will accept. Microsoft has also changed the name from Azure Active Directory to Microsoft Graph for setting domain read permissions.
