EPSON NPD7717-00 Device Authentication Guide for Microsoft Exchange User Guide
Introduction
Due to enhanced security in Microsoft Exchange Online, the previous Basic Authentication method has been discontinued and SMTP authentication (SMTP AUTH) has been disabled by default. Therefore, to use the email service from now on, you will need to use the “OAuth 2.0” authentication method.
If you use the email sending/email notification functions of a printer or scanner, configure the email server settings to use OAuth2.0 authentication.
The following preparation is necessary.
- Enable SMTP AUTH in Exchange Online
- Set up OAuth2.0 authentication for the email server
Make sure that you are using the latest firmware for printers and scanners.
Enabling SMTP AUTH in Exchange Online
Printers and scanners use the SMTP protocol to send emails, so you must enable SMTP AUTH in Exchange Online.
