Enabling DKIM (DomainKeys Identified Mail) in Office 365 involves a few steps, including adding a DKIM signature to your domain’s DNS records and configuring DKIM in the Exchange Online admin center. Here’s a general guide on how to enable DKIM in Office 365:

  1. Verify Your Domain: Before enabling DKIM, you need to verify ownership of your domain in Office 365. This typically involves adding a TXT record to your domain’s DNS settings.
  2. Generate DKIM Keys: In Office 365, DKIM keys are automatically generated for your domain. You don’t need to create these keys manually. However, you should note down the DKIM selector assigned to your domain.
  3. Add DKIM DNS Records: After generating DKIM keys, Office 365 provides you with the necessary DNS records to add to your domain’s DNS settings. These records include a CNAME record and a TXT record with the DKIM signature.
  4. Configure DKIM in Office 365: Once you’ve added the DKIM DNS records, you can proceed to configure DKIM in the Exchange Online admin center:
    • Log in to the Microsoft 365 admin center:
    • Go to the Admin centers > Exchange.
    • In the Exchange admin center, navigate to Protection > DKIM.
    • You should see your domain listed with a status of “Not Configured” or “Pending.” Click on your domain.
    • Follow the instructions to enable DKIM. This typically involves verifying that the DKIM DNS records have been added correctly.
    • Once DKIM is successfully configured, the status should change to “Enabled.”
  5. Verify DKIM Configuration: After enabling DKIM, it’s essential to verify that it’s working correctly:
    • Send an email from your domain to an external email address.
    • Open the email in the recipient’s mailbox and view the email headers.
    • Look for the DKIM-Signature header in the email headers. If DKIM is working correctly, this header should be present and valid.
  6. Monitor DKIM Status: In the Exchange Online admin center, you can monitor the DKIM status for your domain. Check for any issues or warnings that may require attention.
  7. Regular Maintenance: It’s important to regularly monitor and maintain your DKIM configuration. This includes checking for DNS changes, renewing DKIM keys (if necessary), and ensuring that DKIM continues to function correctly.

Keep in mind that the exact steps and options may vary slightly depending on your Office 365 plan and the version of the admin center. Always refer to the official Microsoft documentation or consult with your Office 365 administrator for specific guidance tailored to your environment.
