New Copilot capabilities in Word and strengthened Purview controls for content protection

Here are a few recent updates across Microsoft 365 that are worth keeping an eye on. Two of them focus on Microsoft Word, where Copilot continues to evolve with both deeper document capabilities and expanded AI model choice. The third update shifts over to Purview, strengthening how sensitivity labels control content analysis across Office apps. Together, these changes highlight how document intelligence and data protection are evolving side by side.

Copilot in Word gains deeper document editing capabilities

Microsoft has announced expanded capabilities for Copilot in Word that make it more deeply integrated with core document functionality. These enhancements allow users to perform more advanced editing tasks directly within documents, including working with tracked changes, managing comments, updating document structure, and modifying layout elements while preserving formatting and collaboration history.

The update improves how Copilot interacts with documents in practical scenarios. Users can apply edits with word-level precision using Track Changes, create and manage comments anchored to specific content, and generate structural elements such as tables of contents based on heading styles. Copilot can also manage headers, footers, layout settings, and dynamic fields such as page numbers and dates. Updates are applied directly in the document, and real-time progress feedback provides visibility into more complex, multi-step operations. These capabilities are enabled by default for eligible Copilot users and require no additional configuration.

Public preview rollout began in mid-May 2026 and completed by late June 2026. General availability began in early June 2026 and is expected to complete by early July 2026.

More AI model choice in Copilot for Word

Microsoft has announced expanded AI model support in Microsoft 365 Copilot, allowing organizations to enable Anthropic models alongside existing OpenAI models when working in Microsoft Word. This introduces an additional AI provider that can be used when generating or editing document content, giving organizations more flexibility while maintaining Microsoft’s existing security, privacy, and compliance commitments.

As with earlier Anthropic announcements, it is important to note the following:
Anthropic is made available as a Microsoft sub-processor and can be enabled or disabled in the Microsoft 365 admin center under Copilot settings within the AI providers configuration. The default behavior depends on region. In the EU, EFTA, and the UK, Anthropic is available but disabled by default and must be explicitly enabled. In other regions, it is enabled by default. This makes it important for organizations to review governance, compliance, and data processing considerations before enabling the feature where applicable.

According to the Microsoft Roadmap ID 558440 this should already be available to all.

Expanded enforcement of sensitivity labels for connected experiences

Microsoft has announced an update to an existing sensitivity label setting that controls whether connected experiences can analyze file content. This change expands enforcement so that labeled files are now fully blocked from being sent to any Microsoft connected experiences that analyze content across Word, Excel, and PowerPoint, rather than only a subset of those experiences.

This behavior applies automatically to existing sensitivity labels configured with the setting to prevent content analysis. There is no change required to label configuration, and enforcement will apply by default once the feature rolls out. For organizations using Microsoft Purview, this strengthens content protection by ensuring that labeled data is not processed by connected or AI-powered experiences across supported Office applications. Administrators may still want to review existing labels in Microsoft Purview to confirm alignment with internal data protection policies.

The rollout timeline has been updated. Public preview was originally expected to complete by mid-June 2026 but is now expected to complete by mid-July 2026. General availability was originally planned for early to late June 2026 and is now scheduled to begin in mid-June 2026 and complete by late July 2026.

Timelines for upcoming features may change, so keep an eye on the Message center or the Microsoft 365 roadmap ID 561320 for the most up-to-date release information.
