About this tag
The government compliance tag covers guidance for Microsoft Outlook in regulated government environments, including GCC High and DoD deployments. Current coverage focuses on the new Outlook for Windows pilot beginning July 30, 2026, followed by an expected General Availability rollout starting September 30. The rollout is not an automatic migration: Outlook remains off by default, requires administrative enablement, and is opt-in for users.
