Announcing GA of “Deliver the message to the hosted quarantine” in DLP EXO

Currently available in preview, Microsoft is rolling out a new action for Data Loss Prevention in Exchange Online called “Deliver the message to the hosted quarantine”. 

When this will happen:

Rollout is expected to be complete by late November 2023.

How this will affect your organization:

Previously while managing messages delivered to hosted quarantine, admins had to filter these messages under transport rules. With this update, Microsoft is adding a new column where the messages delivered to quarantine can be viewed under “Data Loss Prevention”.

What you need to do to prepare:

If you are currently not using this action, there is no impact to your organization, but if you are using this action and were monitoring messages that are being quarantined in the Quarantine/ Threat Explorer/Mailflow Status/TPS/Adv Hunting reports you will need to update your Quarantine reason/Policy Type filter from “Transport Rule” to “Data Loss Prevention” to look for the messages that were quarantined because of DLP.

Get started with Data Loss Prevention in the Microsoft Purview compliance portal.
