How to set up a multifunction device or application to send email using Office 365

Article to assist with Setup:

What worked for companies using a static IP from their ISP


  • Authentication: You must be able to configure a user name and password to send email on the device.

  • Mailbox: You must have a licensed Office 365 mailbox to send email from.

  • Transport Layer Security (TLS): Your device must be able to use TLS version 1.0 and above.

  • Port: Port 587 (recommended) or port 25 is required and must be unblocked on your network in your firewall. Some network firewalls or ISPs block ports—especially port 25.

  • We recommend adding an SPF record to avoid having messages flagged as spam. If you are sending from a static IP address, add it to your SPF record in your domain registrar’s DNS settings as follows: v=spf1 ipWANIP ~all
  • Sample record before: v=spf1 ~all
  • Sample Record after edited change: v=spf1 ip4: ~all
