Microsoft Defender for Office 365: Automatic management of allow expiration for Tenant allow block list

Microsoft Defender for Office 365 has made it easier for administrators to manage the allow expiration for the tenant allow block list. The allow rules for the list usually expire after 30 days, which can potentially lead to legitimate emails being blocked. In the latest update, Microsoft will automatically extend or remove the allow rules based on a thorough assessment of the entity in question. This change has been made available for the worldwide (Standard Multi-Tenant), DoD, GCC High, and GCC instances of the web cloud platform. This modification was created on August 30, 2022, and is currently available in the General Availability phase. More information can be found in the Microsoft 365 Roadmap under ID 98134.
