Marcelinho 0 Posted July 22, 2022 Share Posted July 22, 2022 I tried 3 smtp servers: smtp-legacy.office365.com, smtp.office365.com, outlook.office365.com with all combinations of port 25, 587 and TLS, STARTTLS and a working login. None is working with the send test mail. For that matter from within the latest anti virus client it is also not working Link to comment Share on other sites More sharing options...
Solution Marcelinho 0 Posted July 22, 2022 Author Solution Share Posted July 22, 2022 Ok, it is working now, the sender must be the same as the login name. so: outlook.office365.com, with port 587, STARTTLS, automatic autentication and a working O365 login.
