Enable and add DKIM to my domain for Microsoft 365
Follow these Domain Striker steps to enable and add DKIM to my domain for Microsoft 365 for Microsoft 365. Keep credentials handy, save your work, and allow time for DNS or publish changes before you retest.
- Sign in to Domain Striker, open My Products, then select Microsoft 365 and Manage.
- Open the Microsoft 365 admin or Domain Striker guided DKIM screen for your domain.
- Create the DKIM selector CNAME (or TXT) records exactly as shown.
- In Domain Portfolio → DNS, add those records, save, and wait for propagation.
- Return to the wizard and enable DKIM signing, then send a test to a service that shows DKIM pass.
