    Error Code: 53003
    App name: FluentSMTP

    What should I do? My account is owner of the app in AAD.

    We have found that FluentSMTP is trying to connect from Russia, which is blocked for security reasons.

    Location is:
    Nizhnevartovsk, Khanty-Mansiyskiy Avtonomnnyy Okrug, RU

    Please, can you make the connection outside of Russia?

    Hello There,

    Fluent SMTP does not have any country restriction. You can connect Fluent SMTP from any country without any issues. The issue you are facing might be related to outlook subscription types. Can you please check with a free outlook account and let us know if you face any errors?

    Thank you

    Hello Amimul, it’s not from our side. But from the side of Fluent SMTP. When the Fluent Forms Plugin tries to connect to Microsoft 365 from WordPress dashboard to authorize, then Azure AD logging logs it as connection from Russia, which is not allowed in our Organization, so we cant use it. I am not sure, why your plugin try to connect to Our Microsoft 365 from Russia. You tell me please.
