I have a Toshiba copier I'm trying to set up to send email using our office365 acccount. I have tried every single possible combination, and it's still failing.
So I am using this tool called SMTP Diag Tool, and using this tool, it's giving me the reason why it's failing, SMTP protocol error. 504 5.7.4 Unrecognized authentication type
But that still doesn't help me much. I searched online and can't find a solution.
Does anyone know why I can't send emails using my Office365 account on my copier? Below is the output of the diag tool.
Connecting to mail server.
Connected.

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.
