Error code 3101 scan to Email FS-6530

[Zezo54]

I have a problem when scanning to email, an error 3101 appears.
The method used to set up SMTP is direct sending without authentication. Use MX record for Office 365 because the Kyocera FS 6530 does not support TLS.
Port: 25
When running a connection test, OK.
But when I scan from the machine, error 3101 appears

I tried to replace the host name with the IP.
I checked the mxtoolbox website,
also upgrade the firmware
But the problem persists.

Does anyone have an idea to solve this problem?

3101 means the SMTP server responded with an error. I've never set it up using port 25, unauthenticated on Office365, but usually when doing this method, sending inside your domain is the only possibility.

I've done this before without authentication and using port 25 and it worked on the same FS6530 machine
by Office 365.
