Will Microsoft Ending Online Basic Authentication and Exchange Affect Elliott SMTP Emails?
Version: 8.5 & Up
Q - Microsoft announced they will end basic authentication for Azure / 365 and Exchange online by October 1st, 2022. Does that mean Elliott SMTP email support will no longer work with Microsoft Exchange online, and in Outlook 365 or Office 365 after this day?
A - The short answer is that Elliott SMTP email sending will continue to work with Exchange online.
According to the announcement, Microsoft Exchange online will stop supporting most of the basic authentication by Oct 1st, 2022, except SMTP AUTH. Elliott uses SMTP AUTH to communicate when sending emails and will continue to work.
According to Microsoft's explanations, SMTP AUTH will still be available when Basic authentication is permanently disabled on October 1, 2022. The reason why SMTP will still be available is that many multi-function devices (such as printers and scanners) can't be updated to use modern authentication.

It is possible SMTP authentication method is disabled. You can either enable that with PowerShell or go to Exchange on-line admin to enable the mail box to use "Authenticated SMTP". See the following YouTube Video for details:
You should make sure your Elliott version is updated to V8.5b.914 or after to make sure TLS 1.2 is supported. Otherwise, you may receive the following error message:
ERROR: A call to SSPI failed
Also, in Exchange online, SMTP AUTH support should still be enabled. Otherwise, you may receive the following error message in Elliott:
The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.57 Client not authenticated to send mail. Error: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled:
