Sage 300 and Microsoft Graph

SUGGESTED

Has anyone managed to successfully set up and email using the new Microsoft Graph option?

I have gone through the process that Ron Fernandez put up in June.  I can send an email using a powershell command with that setup, but I'm just getting the standard "Mail delivery failed" message when trying to send a test email from Sage.

Does anyone know if there are additional app permissions that need setting up?

Thanks
