Hello Everybody,

We use the plugin AzureOAuthSMTP to send email with Azure online. We configure the plugin as the documentation  www.limesurvey.org/manual/AzureOAuthSMTP_Plugin

We have an error :500: Internal Server Error - Invalid OAuth configurationAn internal error occurred while the Web server was processing your request.
Please contact HESAV Survey to report this problem.

Anybody have an idea ?

Best regards

Can you activate debug mode ?
www.limesurvey.org/manual/Debug_mode

We have exactly the same error. Using the latest LimeSurvey version. I've downgraded the PHP version to 7.4, since on 8.3 couldn't get the debug mode working on the email test page.

Exception: Invalid OAuth configuration
/application/libraries/PluginManager/SmtpOAuthPluginBase.php(409)
    if (empty($config)) {
        throw new \Exception('Invalid OAuth configuration');
    }

Any idea what would be wrong with the configuration?

Maybe check the plugin.log file ?

Hi,
Have you find a solution ?
