    Hi,

    We’re struggling to set up Fluent SMTP with Microsoft.

    We’ve followed the instructions to set up the Outlook account and have the application ID, Client secret & authentication token successfully saved.

    We have also elevated the email account to Global Admin and registered a new application in the azure portal.

    We are still unable to send test emails – the message appears as “Forbidden”

    Do you have any other instructions for Microsoft 365 set-up?

    Many thanks!

    Hello @whonickedmyname,

    I’m here to assist you with the “Forbidden” email issue you’re experiencing while setting up Fluent SMTP with Microsoft Outlook.

    I’ve reviewed the information you provided and the possible solutions suggested by our experts. To address your concern effectively, let’s go through the following steps:

    1. App Callback URL:?Ensure that the URL used to access the API endpoint in Fluent SMTP settings is accurate and includes necessary parameters.
    2. Permissions:?Verify that the sender email address has a Mailbox, is authorized to send emails, and has a valid Office365 subscription.
    3. Account Type:?Double-check that the account type selected when creating the Azure App is “Accounts in any organizational directory (Any Azure AD directory – Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox)”.
    4. Logged-in Account:?When authorizing, ensure that you log in with the same email or account used to create the Azure App.
    5. Domain Verification:?Confirm that your domains are verified within Microsoft Office365.

    If you’ve gone through these steps diligently but still face the issue, I recommend reaching out to Microsoft Office365 Support for further assistance.

    Hope this helps! Please let me know if you have any other questions.
