Microsoft Purview Endpoint Data Loss Prevention is expanding its classification capabilities to detect sensitivity labels on files stored inside archive formats such as ZIP files, improving detection accuracy and giving administrators finer control over how sensitive content within compressed containers is protected. Previously, files packed inside archives could bypass label-based enforcement at the endpoint — this update closes that gap by bringing archive contents under the same DLP policy coverage as uncompressed files. For organizations relying on sensitivity labels as a primary data protection mechanism, this update ensures that compression doesn’t become an unmonitored exfiltration pathway. The feature is currently in development and expected to begin rolling out in August 2026.

Microsoft Edge now supports signing in with a Google account in addition to the existing Microsoft account option, available from the profile menu and Edge sign-in screen on Windows and macOS. Admins can control availability of this feature using the NonMicrosoftAccountSignInEnabled policy, allowing organizations to decide whether non-Microsoft account sign-in is appropriate for their environment. For users who primarily work across Google Workspace and Microsoft 365, this update simplifies browser sign-in without requiring a separate Microsoft account. The feature is currently in development and expected to begin rolling out in July 2026.

Microsoft Teams now allows event organizers save their event configurations as reusable templates in the Events app, making it faster to set up future Teams events without rebuilding settings from scratch each time.

Microsoft Purview is introducing an AI-powered DLP Policy Optimizer that analyzes existing policies, rule structures, and activity signals to surface optimization opportunities that are difficult to detect manually. The optimizer identifies overlapping rules, redundant conditions, misconfigurations, and sources of excessive alert noise — presenting prioritized recommendations with supporting evidence and suggested actions. For compliance teams managing large or complex DLP environments, this update reduces the manual effort required to maintain effective policies while improving precision and reducing false positives. The feature is currently in development and expected to begin rolling out in July 2026.

Microsoft Teams is introducing an External Domains Anomalies Report that gives admins early visibility into unusual or potentially risky interactions with external organizations. By analyzing communication trends and detecting sudden spikes, new domains, or abnormal engagement patterns, the report surfaces actionable insights before risks escalate. As external collaboration expands, this report gives IT teams a proactive tool for identifying data-sharing concerns and security anomalies across tenant boundaries. The feature is currently rolling out for Commercial environments.

Microsoft Teams is adding explicit controls for managing external third-party bots attempting to join meetings. When a bot requests entry, organizers will see a clear representation of it in the lobby — separate from human participants — and must actively admit it through a distinct approval step. This prevents bots from being inadvertently accepted alongside other attendees, giving meeting organizers direct control over what automated processes can access live meeting content. The feature is currently rolling out for Commercial and GCC environments.

Microsoft Purview is expanding Data Loss Prevention enforcement to Microsoft 365 Copilot and Copilot Chat, adding real-time controls that prevent Copilot from processing emails sent from senders external to the organization. When triggered, this control blocks Copilot and agents built in Copilot Studio from using external email content for grounding or responses — reducing the risk of sensitive internal workflows being influenced by unvetted external communication. For organizations where Copilot is actively used to summarize, draft, or reason over email content, this update closes a meaningful gap in data risk management at the point where external and internal communication intersect. The feature is currently in development and expected to begin rolling out in July 2026.

Microsoft Teams is updating Teams Rooms on Android to display the chat panel by default when participants join a meeting in gallery view, ensuring ongoing conversation is immediately visible without manual intervention. Admins can configure this default behavior at the device level, and individual users retain the ability to close the panel with a single tap during meetings. For organizations managing shared room devices, the admin-configurable default provides consistent meeting behavior across rooms without requiring end-user action. The feature is currently in development and expected to begin rolling out in June 2026.

Microsoft is updating dynamic distribution groups in Exchange Online to make group membership available immediately after creation or filter modification, eliminating delays that previously lasted up to two hours. For groups with 5,000 members or fewer, membership is now populated as part of the creation or modification operation itself, reducing administrative friction and ensuring distribution accuracy from the moment a group is configured or updated. For organizations managing large communication structures or time-sensitive distribution needs, this change removes a meaningful operational gap in group management reliability. The feature is currently in development and expected to begin rolling out in May 2026.

Microsoft Purview Content Explorer is adding enhanced filtering controls that allow admins to scope visibility by Sensitive Information Types and sensitivity labels directly from the UI. This update improves the ability to locate and govern specific categories of sensitive content across the organization without requiring broader, unfiltered data views. For compliance and data governance teams managing large content estates, tighter scoping controls reduce investigative noise and support more precise oversight of how sensitive data is classified and distributed. This feature is currently rolling out and expected to complete in April 2026.
