Microsoft Defender for Office 365: Upcoming Changes to Intra-Org Messages
Microsoft Defender for Office 365 is updating the way intra-organizational SCL ratings are assigned for intra-organizational messages. Currently, all intra-organizational messages are marked with SCL -1, but the updated method will assign an SCL rating based on the content and type of message. The ratings will be SCL 1 for non-spam and SCL 5 through 9 for spam. This change, however, will not affect how the messages are delivered. The update will begin rolling out in early April and is expected to be fully implemented by late June. Admins don't need to take any additional actions as these changes will be reflected in Threat Protection Status (TPS) and Mail Flow reports. This document describes the updated function of the SFV:SKI field in the X-Forefront-Antispam-Report.
