M365 Changelog: (Updated) Microsoft Defender for Office 365: Hourly option for notifications
MC383901 — Updated May 9, 2023: Microsoft has updated the message to ensure visibility. Thank you for your patience.
Microsoft is adding a new hourly option to end user quarantine notifications, which will allow users to rely on receiving prompt notifications about quarantined items when appropriate. With this feature, users will be updated frequently once new items land in their quarantine folder.

When this will happen:
Standard: will begin rolling out in late November 2022 (previously early October 2022) and be completed by late June 2023 (previously late February 2023).
Government: will begin rolling out in early June 2023 (previously early July 2023) and be completed by late June 2023 (previously late July 2023).
How this will affect your organization:
