The latest release of ((OTRS)) Community Edition comes with support for OAuth2 authentication for email accounts used to receive email tickets and send messages. There are built-in configuration templates for two most popular email service providers: Gmail and Microsoft 365.

This feature might be especially important if you are using OTRS CE with a Microsoft 365 email account, because Microsoft is disabling basic (password-based) authentication in January 2023. If your email accounts are still configured to make use of passwords, you should switch to OAuth2 soon.

The new documentation for OTRS CE that we started working on now includes step-by-step instructions on OAuth2 configuration for Microsoft 365 and Gmail users. Today we have also published an instructional video that shows the configuration process for Microsoft 365 accounts — see it below or on YouTube.
