Scan to mail from mfp device through SMTP relay connector fails

Hi,

 

As a service technician for multifunctional devices I see more and more companies using an SMTP connector to let the device use scan to mail trough office 365 on port 25. So I tried to set this up for my own home device (Kyocera), instead of using just the ISP smtp, but it's not working and I don't really know why......

 

* First I made a connector on the 365 admin platform, from organisation mailserver to office 365, and added my public IP @ home. 

* On the mfp device STARTTLS is on, and as SMTP i filled in COMPANYNAME.mail.protection.outlook.com with port 25.

* The mfp device is using my ISP dns servers, but also tried google without any result.

 

Every test connection I want to try failed on the mfp device but I can not see what the reason should be.

 

Anyone?

 

Thx in advance,

  • Hey Froota ,

     

    Is there a firewall in picture ? Check the firewall to see if there is outbound traffic to office 365, see if it is being dropped for any reason.

  • From your explanation seems like you have done correct configuration on both your device and O365, however issues may occur when O365 refuses to connect due to IPs reputation.
    Try below and see if it throws any error :-
    telnet COMPANYNAME.mail.protection.outlook.com 25
