Configure SMTP Devices for Office 365

Many devices that send emails on your behalf utilise SMTP services to send those emails. If an email account is provided through Office 365, emails can therefore be routed through that account.

SMTP Settings

For SMTP, the following settings must be used:

 Port: 587
 Security: SSL/TLS
 Username: Office 365 Username
 Password: Office 365 Password

Bits to Note

Office 365 enforces TLS 1.2 on SMTP connections. Your device must support TLS 1.2 or later to work in this setup.

The Username must be for a licenced Exchange Online user. If the user needs to send as another address, you should grant that user permissions to send as that address. Sent Items will be placed in the mailbox of the original user.

If an account is configured with Multi-Factor Authentication, they may need to use an App Password unless the SMTP application supports Modern Authentication.
