Commercial Priority Update
Week of June 4, 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 365 app: New Copilot Notebooks design in the Microsoft 365 Copilot App
The new Copilot Notebooks design in the Microsoft 365 Copilot app now lets users organize related chats, output creations, and references into a persistent AI workspace. Copilot uses the Notebook’s accumulated context to ground responses, so work continues across sessions instead of starting over each time. While this is the quicker, light-weight Notebooks experience, you can still find the fuller, workspace-forward experience in OneNote.

Microsoft Purview: Endpoint Data Loss Prevention – Allow customer to scope JIT Audit to specific user or user group

Microsoft Purview: Endpoint Data Loss Prevention – Ability to protect files stored in the excluded folders in Windows

Endpoint Data Loss Prevention — Endpoint DLP now supports a pre curated list of file extensions for the file extension condition
Endpoint DLP now includes a pre curated list of file extensions for the file extension condition. Previously, file extensions were entered as free form text, which could result in unsupported or non-scannable extensions being used. This could lead to gaps in protection and increase processing overhead on endpoints. With the pre curated list, you can select only supported file extensions. This helps improve policy reliability and reduces unnecessary processing on endpoints.

Microsoft Copilot (Microsoft 365): Declarative agents with Actions available in GCC High and DoD

These actions are powered through API plugins, MCP tools, and enterprise connectors, allowing seamless integration with line-of-business applications and services. The Copilot platform dynamically reasons over available actions and selects the appropriate tool to fulfill user intent, enabling multi-step workflows such as creating records, submitting requests, or triggering business processes within a single conversational flow
