BC On Premise - Email Not Sent error

(0) ShareShare
ReportReport
Posted on by Nick Webb 640

I've managed to set-up a 'Current User' Email Account and accompanying AAD App Registration. When I click the [Verify Registration] button on the Email Application AAD Registration page in BC it reports 'Success! Your authentication was verified.'

However, when I try and send an email via the 'Email Editor (13, Document) page, it reports:-

The email was not sent because of the following error: "The mailbox is either inactive, soft-deleted, or is hosted on-premise." Depending on the error, you might need to contact your administrator.

This error is also encountered when attempting to send a test email from the Email Accounts page.

How do I get this working?

    Thanks Inge and Zhu for your suggestions. I value your opinions. Honestly, in the past, I've got more solutions from this forum than I have from a Microsoft Technical Support ticket. Anyway, I 've come up with a clunky solution. As I only work for a small company, I've created an Smtp Email Account for each employee with their email address stored inside, and I've customised my code to conditionally choose the appropriate Email Account. So, in short, I've bypassed Current User and 365 email account types.

    Hi, I agree with Igne, if you have tried all the methods provided in the MS Docs below and the problem has not been solved, it is recommended to submit an SR to Microsoft. This may be a problem with the server, network, firewall, mail server settings, etc.

    https://docs.microsoft.com/en-us/dynamics365/business-central/admin-how-setup-email#setting-up-email-for-business-central-on-premises

    Hope this helps as well.

    Thanks.

    Since this involves more solutions than just Business Central and you are not able to get it to work by following the documentation i would recommend you reach out to your partner and seek their help. They can if needed open a support case with Microsoft and that can involve both BC, Azure AD and Exchange resources.

    With your business need for e-mail handling it would maybe be a good idea also to consider going to BC online unless you have very specific needs that requires you to run BC on prem.

    ... remembering that we've lost the ability to change the From Address in code as this threads bears out:-

    Hi Inge,

    I'm already using the SMTP connector. That's working and is good for some parts of the system, but it sends from a fixed email address. We have a particular requirement in a different part of the system to send from the current user's email address. Hence the need for the Current User Email Account.

    Thanks

    Nick

    In your case i think you need to use the SMTP connector.

    Please look at this doc:

    The mailbox concerned is hosted on-premise. Does that mean what I’m trying is a flawed concept?

    Am I missing a step?

    I found this error detail in the Event Viewer:-

    Message Could not send the email {09D6CC61-F0B0-4FC3-B664-BFE364BE81F9} because of the following error: Use ERROR with a text constant to improve telemetry details.
