Email Account Used in F&O Being Flagged for Spam

(0) ShareShare
ReportReport
Posted on by 78 User Group Leader

Since our go-live (Nov 2021), we are using Microsoft Online​ Exchange (smtp.office365.com) to route email out of D365 F&O (version 10.0.25).

We have a few different email templates sending emails – all of which use a different email address (xxxx@domain.com).  However, all of these email addresses ‘send as’ the master account out of Exchange.  Within the past month, the master email account we use to send emails has been flagged by Microsoft as having sent spam which deactivates the email account.  Emails are still being sent out of F&O, but since the account is flagged, recipients are not receiving emails.  We have to reactivate the account in Exchange and then resend all the emails that were sent while the account was flagged.

Has anyone else had this issue?  If so, have you need able to resolve?

What are you using to route emails from F&O if not Exchange?

We are of the understanding that only one Exchange account can be the ‘master’ account.  Can there be two accounts allowed to send email from F&O using Exchange?

    O365 limits outbound emails to certain rates ( not sure the limits ). Above that threshold, account is marked as spam. You could raise a ticket to O365 get better details. If is related to that or not.

    You can use any SMTP provider linked to D365. Some SMTP provide better rates under bulk emails. We already setup other e-mail providers to overcome this limitation. You can use any account in O365 that as permissions to send by SMTP.

    Thank you.  What other email providers have you used and do you prefer one over the other?

    First I would recommend checking why account is being marked as spam, due to volume of e-mails from D365 or other factor. I would open a support case in MS.

    I already setup SMTP in D365 with Gmail Enterprise account, SendGrid, etc.

    When that happened, we opened a ticket to Microsoft and tell why we use this e-mail address.
