Some mails do not get send

Hello there,

Please accept my apology for the delay in getting back to you. Can you please check the failed email and see if there are any error messages? Fluent SMTP has the email log option and if you click on the details of the failed email, you will see that there are details of the failed emails. If you find any errors, please share this with us.

Thank you

Hello,

Thank you for getting back to me. I just checked, this is the error:

{ “code”: 422, “message”: “Unauthorized”, “errors”: [ “Unauthorized” ], “fallback”: “Tried to send using fallback but failed. webshop name <[email protected]>”, “fallback_response”: { “code”: 422, “message”: “Unauthorized”, “errors”: [ “Unauthorized” ] } }

I changed the real webshop name and e-mail to “webshop name” for privacy reasons, hope that’s okay.

Thank you in advance.

Hello @werfewr,

Could you please confirm if the issue is resolved now? If it is still ongoing, we would be happy to assist you further.

Your cooperation is greatly appreciated. Please let us know if you have any other questions or concerns.

The issue still remains. The website is not yet on the real domain, so maybe that has something to do with it?

Hello @tiffanyvdhoven ,

I understand that you’re having issues with some emails not being sent through Fluent SMTP.

It seems that the issue could be related to a Microsoft SMTP connection issue. Here are a few things you can check:

1. Incorrect App Callback URL:?Double-check the URL you use to access the API endpoint provided by Fluent SMTP settings.
2. Insufficient permissions:?Ensure that the email address you’re using as the sender has a Mailbox created, permission to send emails, and a valid Office365 subscription.
3. Incorrect Account Type:?Verify that you’ve selected the correct account type when creating the Azure App. It should be “Accounts in any organizational directory (Any Azure AD directory – Multitenant) and personal Microsoft accounts (e.g., Skype, Xbox).”
4. Incorrect Logged-in Account:?When authorizing, use the same email or account used to create the Azure App.
5. Domain Verification:?Reconfirm that your domains are verified within Microsoft Office365.

If you’ve checked these points and the issue persists, refer to the Office 365 API documentation or reach out to Microsoft Office 365 Support for further assistance.

Please let me know if you have any other questions or require further assistance.
