Guidance Requested: Email Setup in Business Central (No-Reply Account)

Posted on by 10

Hi everyone,

I’m having some difficulty setting up email accounts for Business Central. Specifically, I want to configure a no-reply account so that all emails sent from BC will use this account.

I followed Mr. Zhu’s blog on the setup process, but I’m a bit confused about what steps I need to take. You can find the blog here: Link.

I’m encountering the following error message:

"Could not send the email. The ***** account does not have 'Send As' permissions on your mail server for the ***** account."

"The SMTP server rejected the authentication request, as the authentication data is incorrect. Verify that your username and password are correct and that the SMTP server supports the specified authentication type (OAuth 2.0). SMTP error code: 535."

  1. Basic Authentication: Can Basic Authentication still be used? If so, what setup is required to enable it?

  2. OAuth2 Authentication: If I want to use OAuth2, what setup is necessary? I found the Microsoft article here, but it’s a bit unclear. I also noticed that there is no "Email Application" registration in Microsoft Entra ID for BC.

Has anyone had experience with this? Any guidance or clarification would be greatly appreciated!

Thank you!

    Hi I am also doing some setup OAuth SMTP in our sandbox, but got this error.
     
    Could not authenticate on the SMTP server.

    451: 4.7.0 Temporary server error. Please try again later. PRX5 [SI1PR02CA0041.apcprd02.prod.outlook.com 2024-10-02T09:31:07.861Z 08DCE24D17B9CD49]
     
     
    I have tried to follow all these steps

    Sorry, I'm not an expert on exchanges either.
    First of all, Basic Authentication is still available, and Microsoft has not mentioned the date of its deprecation.
    As for OAuth2 Authentication, I have tested it in three environments. If the user you set is in the same domain and includes an Office 365 license, you can set it up as follows.
    As for Email Microsoft Entra application registration, this page does exist and can be opened directly via the URL"?page=4509". But as I tested above, it can be sent without setting this. I don't know if this is a bug.
     
    You can also test it.
    Thanks

    Please make sure if you already set this field true
