Since January 24, 2023, this processor stop working, we are wondering if this is related to OAuth new feature that Microsoft is implementing???? The other processor used to send emails (PutEmail) still working. Can someone give me an explanation?

    Hi Jose,

    This is most likely due to the depreciation of basic authentication:

    You can check if you have disabled basic authentication via Admin Portal:

    In the Microsoft 365 admin center, go to Settings > Org Settings > Modern Authentication. In the Modern authentication flyout that appears, click to enable or disable Turn on modern authentication for Outlook 2013 for Windows and later (recommended).
