GCC High Priority Update
Week of June 18, 2026
Microsoft Purview is adding AI-powered investigation for Endpoint DLP policy sync and device health, giving admins visibility into whether DLP protection is actually deployed and enforced across their devices. The system proactively identifies impacted devices, explains the root cause of sync failures, and recommends specific actions to resolve issues — closing the gap between assuming devices are protected and confirming it. For organizations managing DLP at scale, this update turns a previously manual troubleshooting process into a guided, AI-assisted diagnosis. The feature is currently in development and expected to begin rolling out in August 2026.

Microsoft Teams: Profanity filter is disabled by default for captions
We are updating the default profanity filter setting for live captions from On to Off across Teams meetings, calls, events, and Microsoft Teams Rooms (MTR) devices to improve accessibility and align with EU requirements. This change will only affect users who have never configured their live captions profanity filter preference. Users who have already set their preference will keep their current setting. As a result, some users may begin seeing unfiltered profanity in live captions by default after this rollout. Users can update this preference in settings at any time.
