Microsoft Defender for Office 365: Tenant Allow/Block List domain & addresses block to send inbound emails to admin quarantine

Microsoft Defender for Office 365: Tenant Allow/Block List domain & addresses block to send inbound emails to admin quarantine

The latest update to Microsoft Defender for Office 365 addresses an important issue concerning the Tenant Allow/Block List. Previously, when a domain or email address was blocked, incoming emails from those sources would be marked with SCL:9, but they would still be delivered to end users' inboxes. Now, with the new update, any inbound messages from domains or email addresses on the Tenant Allow/Block List will be sent to admin quarantine, providing better protection against malicious messages. This update is set to be released in March CY2023 and is available on a worldwide platform, including the Standard Multi-Tenant, GCC High, DoD, and GCC instances.

For users of Microsoft Defender for Office 365, this update delivers an important improvement in security and peace of mind. With the changes implemented, users can expect a more effective safeguard against harmful messages than before.

Find out more about this update and its release details in the post here.
