How to Set Up DKIM for Microsoft Dynamics 365?

DKIM prevents email spoofing by signing messages with a digital signature: a crypto key ties an organization to an email address. It is a standard that, along with DMARC, helps combat spam, phishing, and spoofing attacks.

Microsoft Dynamics 365 supports DKIM signing for your custom domain. Here is how you can do that: 

Enabling DKIM Authentication for Dynamics 365

  • Login to your Dynamics 365 account

  • Go to Settings > Email marketing > Domain authentication

  • On the command bar, click on New

  • Start the process of adding a new domain

  • As a new authenticated domain record opens, you need to:

  1. Enter your domain name, for the domain you want to enable DKIM. Please enter the domain name without https:// or www, e.g:

  1. Select the check box adjacent to “Enable for email sending” 

  1. Select this check box adjacent to “Enable for forms hosting” 

  • Click on Save from the command bar. 

  • With this step, Dynamics 365 saves your new record and creates a set of DKIM keys for your specified domain with is displayed on your screen as the page automatically reloads.

  • Contact your DNS provider to help you host your DKIM record in your DNS. Alternatively, if you have access to your DNS you can publish the records on your own. 

  • When done, head back to your Dynamics 365 account and click on the Confirm DNS registration button. This allows D365 to verify whether your domain has been successfully set up with DKIM. 

Note: On successful registration, you will receive a confirmation message from D365’s support team. If you don’t receive the confirmation right away, retry again later since the process of registration can take up to 24 hours. 

If you are facing problems with your DKIM configuration, check your record now using our free DKIM record lookup tool.
