Invoice Emails not arriving at destination

Posted on by Community member 24
Hello everybody, I hope you are well.
We've newly started to use Business Central and so far things are going very well.
However, we've noticed some customers have not been receiving our invoices via email, mainly those who use Office365 for email. We also use Office365, and Business Central is configured to use the user's account to send the email via Office365 so I cannot understand why this is happening. Our Office 365 is set up correctly, with valid SPF, DKIM, DMARC, MTA-STS configurations in place. We've never had problems sending emails before to these addresses, and /conversational/ emails still go to these customers correctly - it's just the invoices that are failing.
I can see the invoice emails are being transmitted and accepted by the recipients side successfully, so I cannot see any errors in our email transaction logs to work out why this is.
Invoices to non-O365 accounts appear to be received fine.

Can anybody help me with where to look next? I've requested email transaction logs from the recipients IT but have not yet received anything in response.
 
Thanks in advance

    I do not have an answer but we are having the same problem, we are working on verifying all the SPF and DKIM settings, but business central is doing something with the linked account. We can send an email in outlook with the exact information and attachment and customer gets the email, but if we send from BC, it goes to spam.

    We had to change our default subject field and change the text in the email body, too much information in the body of the invoice was getting our emails tagged as spam.

    We have the exact same issue, and we have determined that if we put a body in the e-mail with the invoice it does not reach the receiver (for office 365), but if we don't put anything in the body it works fine. It does not matter if the body is created from a word template or entered manually by a user when sending the e-mail from BC, it never reaches the receiver if the e-mail body is not empty. 
    If someone have managed to fix this, I would be interested in knowing how.

    Hello,
     
    So if I am able to understand correctly - the invoices via email are not being sent ?
     
    Can we reconfigure the email accounts and Office 365 again and check ?

    if the emails are sending out correctly to customers it mean the email setting is correct in general. But you could take a look if anything is set up under document layout on customer card. You could also set up the invoice with recipient email to test there.
    Still this seems to be a MS issue and I would suggest you to log a ticket to MS.

    To anybody viewing this now, I've kind of resigned myself to the point that Microsoft isn't really caring about this... and after a period of time invoices are now sending fine. 
    I would suspect this is more down to "all of a sudden" Microsoft handling many invoice emails from a company where it's never received them before and so treating them as suspicious. After some time, and trust is built they're started to ignore them.
     
    So basically, my money is on this being an over-eager spam prevention technique rather than an actual issue.
