Microsoft 365 Defender: Tenant Blocks via Admin Submission

We are excited to announce that in Microsoft 365 Defender, you can now block suspicious entities when submitting emails, URLs, or attachments for Microsoft to review.

This message is associated with Microsoft 365 Roadmap ID 98920

When this will happen:

We will begin rolling out in late September and expect to complete by early October.

How this will affect your organization:

This won’t affect your organization in any way other than making it easy to create blocks via Tenant allow/block list while making a malicious URL, email attachment or email submission. 

What you need to do to prepare:

You need to inform the individual or organization who is making submissions today. We recommend updating training documentation as appropriate. To learn more, please visit this page
