PFU has been made aware of Microsoft's decision to discontinue support for basic authentication for sending emails using the SMTP protocol in Exchange Online after March 2026. Following this change, OAuth2.0 authentication will be required on applications and devices when using the SMTP protocol to send emails.
This notice explains which RICOH fi and SP Series product functions are affected by the deprecation and the planned schedule for OAuth2.0 authentication support.
1. Affected functions
After basic authentication is discontinued, an error will occur when sending emails or internet fax.
If you do not use these functions, or if you are using an email account other than Microsoft's Exchange Online as the destination for email or fax transmission, you will not be affected.
Additionally, you can avoid any impact by either switching to a method that does not use email or fax transmission, or by using an email or fax service other than Exchange Online.
Please note that if you are using Microsoft Exchange Server on-premises as your mail server, you will not be affected.
