SMTP: Connector Exchange on Sharp printer

Question

Hello everyone,I am having a problem sending e-mail from the "Scan to e-mail" function of several customers' photocopiers, but I have complied with the recommendations of the Microsoft article that recommends:Create an Exchange SMTP connector with the company's public IP address.Configuring the photocopier with the MX server of the Office 365 holder.Setting port 25, activating SSL/TLS and disabling SMTP authentication.Entering the correct SPF/TXT value on the DNS provider with the ip4:202.22.X.X.XLThe photocopier indicates that the connection to the SMTP server is functional, but when I send e-mail to an address that is part of the Office 365 holder, the Sharp MX-C304W photocopier generates an "80-0000" error that corresponds to an authentication error, or a wrong identifier.

Has anyone ever encountered this error?

Hi，@Vincent Heidelberger

Thank you for connecting with us in Microsoft community.

Based on your description, you seem to be using Option 3.

Do you have to send emails to external recipients? If not, it is recommended that you choose option 2 for easier implementation.

You can refer to this link for details:https://learn.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365?source=recommendations#option-2-send-mail-directly-from-your-printer-or-application-to-microsoft-365-or-office-365-direct-send

Hello, thank you for your response. I have already configured the connector as it is written in the procedure and it worked. It is only for 2 weeks that it no longer works while I have not changed the configuration.I specify that I do it for several printers and it worked
