Microsoft Defender XDR

Summary

Microsoft Defender XDR is introducing a simplified DKIM setup for better domain protection, with a rollout from mid-June to late September 2024. The update includes easier DKIM activation during domain registration and a redesigned DKIM page for improved information visibility. No action is required for preparation.

Details

Updated September 12, 2024: We have updated the rollout timeline below. Thank you for your patience.

This feature update provides improvements to how you can protect your domains from spoofing with DKIM (DomainKeys Identified Mail). 

When this will happen:

General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out mid-June 2024 and expect to complete by late September 2024 (previously late August).

How this will affect your organization:

There are two major updates, as shown below.

Easier DKIM activation during domain registration

Now, you can directly enable DKIM from the domain page in the admin portal during the domain registration process. Click to select the DomainKeys Identified Mail (DKIM) box below, and the wizard will guide you through the steps to publish and enable DKIM.


Revamped DKIM page

The DKIM page has been redesigned to provide more information at a glance. You can now easily see the status of DKIM and enable it by selecting the toggle, as shown below.


What you need to do to prepare:

This rollout will happen automatically. You may want to notify your security or email admin about this change and update any relevant documentation as appropriate.
