Hello I really thank you! very useful and perfect explained info, I was able to send emails But now I am exploring a topic related to Oracle APEX and Microsoft Exchange Online, Microsoft is requesting to upgrade to using oAuth2 this 2025, have you ever been asked to upgrade to oAuth2 on an instance that uses Microsoft Exchange Online for sending e-mail? If not, do you think it is possible to configure Microsoft Exchange Online with oAuth2 using Ords? I you can help me with this question I think it will be very complicated but I don't know How to start facing the challenge
