jonash tomtom You can create App Passwords in the Azure/Intune for your Mail Account to auth. ITFlow and other SMTP auth Apps.
magixnetworks I create a mail connector in Exchange authenticated by IP Address and use the MX record host as the mail server, port 25, no auth. Also add your ITFLow instance public IP address to your SFP record so things don't get blocked.
tomtom magixnetworks I have tried to do the connector setup before but didn't put a lot of time into it or have much success, i will look into this again.
