Connection Settings
The connection settings determines how to connect to the Exchange Online organization.
Service Principal (Certificate)
This is the recommended authentication method.
Service Principal (Client Secret)
This method uses a client secret (password) for security - which is easier to share however is less secure than the certificate method.
This method uses a username and password and has been deprecated and is not recommended.
To scan interactivity instead using multi-factor authentication use the Microsoft 365 Agent UI.
