We are trying to configure Maileater for oAuth 2.0 authentication according to instructions in KB article Oauth Setup for Maileater
On the Register an application window, under Supported account types, their options are:
- Accounts in this organizational directory only ([company] only - Single tenant)
- Accounts in any organizational directory (Any Azure AD directory - Multitenant)
- Accounts in any organizational directory (Any Azure AD directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)
- Personal Microsoft accounts only
Our security department require that we select the first option (Single tenant), but when we select that we see this error message when requesting the token:
