MC468486: Microsoft Defender for Office 365: Migration of quarantine notification frequencies

This communication is an extension of the previous communication in MC383901.

We are updating the frequency interval available for user quarantine notification.

This message is associated with Microsoft 365 Roadmap ID 93304.

We are adding a new hourly option to end user notifications, allowing users to be able to rely on prompt notification about quarantined items when appropriate. With this feature users can be rest assured that they will be updated frequently once new items lands on their quarantine folder.

When this will happen

Standard: will begin rolling out in late November and be completed by late February 2023

  • Within 1 day
  • Within 2 days
  • Within 3days – current default

For customers that currently have notification frequencies > 1 day and < 7days, we will migrate to 1 day (i.e daily) For customers that currently have notification frequencies > 7 days, we will migrate to 7 days (i.e weekly)

What you need to do to prepare

Admins should update their quarantine global policy configuration frequency as they see fit and training documentation
