miten saan SMTP palvelimen käyttöön?

That error usually means the camera’s email settings have not been configured correctly, or the email provider is rejecting the connection. You want to set it up using outlook.com, is that right?

You will need to go into the camera’s settings and look for something like Email > SMTP, Mail Server, or Alarm Email. This can be different from model to model. Please refer to your camera's user guide.

For an Outlook.com account, use:

SMTP server: smtp-mail.outlook.com

Port: 587

Encryption/security: STARTTLS or TLS

Authentication: Yes

Username: the full Outlook.com email address

Password: the Microsoft account password

Microsoft now requires modern authentication for Outlook.com. If this is an older security camera that only supports a basic username/password SMTP connection, it will not work with Outlook.com.

So I would first try the settings above. If it still says the SMTP server is not in use or cannot authenticate, please check with the camera manufacturer support, ask them if their camera settings can support OAuth2/Modern Authentication.
