I'm trying to send an email with the Send Mail script step. Using SMTP for an Office 365 account and getting a "The authentication failed." error message.
The SMTP settings are:
Outgoing SMTP Server: "smtp.office365.com"
Connection encryption: TLS
Authentication: Plain Password
User Name: "email@example.com"
The username/password I'm using are correct and work when logging in via browser. Any ideas on what I've got wrong?
