Hi, we are trying to configure app registration between our application and Outlook. We created a Client Secret, but not sure what to do with it after that. We have another profile someone else created that IS working but they're no longer with the company. What do we need to do with the secret ID and key? We thought we had to enter it into a vault, however, our other application is working fine without that and we don't even have a vault defined. Currently, when using the application that isn't working, when we try and send an email we get "AADSTS700016: Application with identifier '

Microsoft Entra ID

    Hi @Terry Eaton ,

    The error means that the application isn't registered, or the wrong application information is included in the registration. Make sure that the application with that identifier is registered under Azure AD > App registrations. (You can do this by pasting the identifier from the error message searching for that identifier there.) Then make sure that the correct Client ID is specified in the application itself (as the Application ID) and matches what you have configured for the registration. Also, please make sure that you code references the correct tenant in the application settings.

    In addition, make sure that the app ID/client ID is updated under the Identity in App Service > Your app > Settings > Authentication > Identity Provider > +Add provider
