I'm trying to set up an external application using Microsoft graph authentication in order to authenticate a shared mailbox in Microsoft. In the external applications, there's an option to select Microsoft Graph, but in the email authentication drop-down when setting up a new email account the only options are OAuth.
Can anyone advise on this?
