Add CNAME Records to Your DNS<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Now, add the copied CNAME records to your DNS management console (this could be your domain registrar or hosting provider). on my side i use Cloudflare DNS, (<a href=\"https:\/\/dash.cloudflare.com\/\">https:\/\/dash.cloudflare.com\/<\/a>)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.jameseduard.com\/wp-content\/uploads\/2025\/01\/image-5-1050x550.png\" alt=\"\" class=\"wp-image-8794\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><br><br><strong>5. Enable DKIM Signing<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After adding the CNAME records:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Return to the Microsoft 365 Defender portal.<\/li>\n\n\n\n<li>In the DKIM settings, select your domain and click&nbsp;<strong>Enable<\/strong>.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.jameseduard.com\/wp-content\/uploads\/2025\/01\/image-6-1050x550.png\" alt=\"\" class=\"wp-image-8795\"\/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">6. Verify DKIM Configuration<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Finally, verify that your DKIM configuration is correct:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use online tools like MXToolbox to check your DKIM setup.<\/li>\n\n\n\n<li>Send a test email to ensure that DKIM signing is working as expected.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Enabling DKIM in Microsoft Defender for Office 365 is a crucial step in securing your email communications.
