We are approximately a month away from the deprecation of Basic authentication in Exchange Online/Office 365. This becomes permanent on October 1, 2022 and will cause our existing Exchange emailing in Microsoft Dynamics GP to fail.
We want to send a reminder with all the information that will help you begin to use Modern Authentication, which is going to be required, in order to continue using Exchange email in the Dynamics GP application.

The Modern Authentication was added to Dynamics GP in the October 2020 release / 18.3.1173, so if you're on that version of Dynamics GP currently or later, you can implement this functionality. However, we do recommend upgrading to the latest release of the application as there have been many items fixed around Modern Authentication.
If you are not using Modern Authentication after Oct. 1, 2022, users will begin receiving ‘Login Failed’ messages when they enter their Exchange credentials to authenticate when attempting to email or use email setup in the Dynamics GP application. Once this occurs, there is no other work-around or fix that will be available. This excludes Exchange on-prem, if you are using that.
Any further information regarding email in Microsoft Dynamics GP can be found in our email troubleshooting document at this link:

If you have issues setting up Modern Authentication, specifically getting errors when attempting to save the changes and then enter your account for Azure to synch Dynamics GP with the Client ID, the following blog also has some good troubleshooting information in it:

If you have any questions, please let us know. We want to make sure everyone is prepared for this upcoming change and not caught with email not working in Dynamics GP.
