YOU NEED TO ADD: Using modern authentication (OAuth)
What's changing?
Microsoft have retired Basic Authentication on Outlook.com, and Google are retiring Basic Authentication on Gmail.
This means that if you use SMTP to email from your software, via Outlook.com or Gmail, you need to update your configuration. To continue to send emails using software:
- With a Microsoft email account, you need to send using classic Outlook
- With a Gmail email account, you need to either send using classic Outlook, or use an App Password to continue to use SMTP
