SMTP Relay Server

Third party devices

Third party devices such as fax machines, scan to email and voicemail systems may need a SMTP server to send messages. Office 365 requires authentication when sending email. This means you will need to use the username and password of a licensed user to send messages.

If you have Enterprise level plan you may purchase a kiosk license which has 2 Gb limit and can be used as a SMTP relay server. If you have questions about this license please email
