Microsoft 365 Copilot March 2026 update

User Capabilities

Video recap of meetings in Copilot Chat

When users ask Copilot Chat to summarise a meeting, they’ll now get a video recap alongside the written recap. Video recap transforms the meeting summary into a narrated highlight reel, combining key takeaways with short, relevant clips that bring important moments to life. Video recap is available in Copilot Chat and Microsoft Clipchamp web player for meetings that are at least 10 minutes long with recording enabled. Video recap will launch initially in English only. This feature is rolling out in March.

Researcher app branding and Notebooks improvements for the Copilot app

Users can convert Researcher reports to PowerPoint, a PDF, an infographic, or an audio overview, adapting insights to every audience in one click, without redoing the work.  This feature rolled out in March.

Admins can now add a branded footer to the Microsoft 365 Copilot app for their organisation. This footer appears at the bottom of the Copilot Chat screen in the app and helps build trust that they are using an approved, organisation-managed AI tool. The footer can be configured for users in the Microsoft 365 admin center. This feature rolled out in March.

Copilot Notebooks features a new, revamped user experience that makes navigating and working in Notebooks more intuitive. The updates bring references, content in Copilot Pages, and Copilot chats into one seamless, side-by-side view.

Audio recap is now available in seven additional languages. In addition to English, users can now generate and listen to AI-powered audio summaries in Chinese, French, German, Italian, Japanese, Portuguese, and Spanish. This feature rolled out in March.

AI in SharePoint

AI in SharePoint brings agentic building and content intelligence directly into SharePoint. Teams can plan and build sites, libraries, pages, and lists using natural language  AI in SharePoint rolled out to Public Preview in March and is rolling out worldwide in May.

AI in SharePoint automatically extracts and applies metadata, adapts libraries as content changes, and helps ensure information is structured to support accurate Copilot and agent experiences across Microsoft 365. The preview is powered by Anthropic’s Claude model. These features rolled out to Public Preview in March and are rolling out worldwide in May.

Work IQ Context and editing local workbooks with Copilot in Excel

When users are editing with Copilot in Excel, Work IQ automatically brings in the most relevant context—from emails, meetings, chats, files—without requiring users to manually reference them. The feature rolled out in March.

Copilot can now make multi-step edits to modern Excel workbooks stored locally on devices across Windows and Mac platforms. This feature rolled out in March.

Citations display for Copilot in Word

Now, when users are editing with Copilot in Word, citations are automatically displayed whenever responses incorporate information from web content or Work IQ sources. This helps users easily verify and track the origins of content, improving transparency and confidence in the document’s accuracy, and ensuring reliable referencing for all edits with Copilot. This feature rolled out in March.

Standardise format with Copilot in PowerPoint

By enabling ‘Edit with Copilot’ in PowerPoint, users can quickly standardise a presentation’s appearance by automatically updating fonts, font sizes, and bullet styles across all slides at once, eliminating the need for tedious, manual adjustments. This feature rolled out on the web in March and is rolling out on Windows and Mac soon.

Copilot Controls

Safeguard web searches and prompts with Microsoft Purview Data Loss Prevention

Microsoft Purview Data Loss Prevention (DLP) for Microsoft 365 Copilot and Copilot Chat is expanding to safeguard web searches containing sensitive data. This feature rolled out to Public Preview in March and is rolling out worldwide in June.

Microsoft Purview DLP is further expanding to safeguard prompts, helping organisations prevent sensitive information from being used in Copilot prompts. Admins can define policies that detect and restrict Copilot from responding to prompts, connecting to internal data sources, and performing web searches if the prompt contains sensitive data​ such as financial data, national IDs, bank numbers, or custom SITs. This feature is rolling out in March.

Manage authoritative sources, high-usage users, and domain exclusion in the Microsoft 365 admin center.

Admins can now manage authoritative sources within the Copilot Search experience in the Microsoft 365 admin center. This capability enables admins to designate SharePoint Online sites as authoritative content for their organisation, helping enhance the relevance and ranking of these sites in Copilot search results. This feature is rolling out in April.

High‑usage users are a new category that helps IT and finance teams quickly identify individuals driving high consumption across Copilot usage‑based services (i.e. pay-as-you-go services). By surfacing high‑usage patterns in one place, admins gain early visibility into potential cost drivers, enabling faster investigation and informed license optimisation decisions. This feature was rolled out in March.

Domain exclusion for web grounding lets admins specify a limited set of sites to exclude from web grounding in Microsoft 365 Copilot and Copilot Chat, giving IT teams control over which external web sources Copilot can reference when generating responses, supporting compliance and content governance requirements. This feature is rolling out in April.

Tracking satisfaction, intent, and usage with Copilot Dashboard

Analysts can now track user satisfaction of Microsoft 365 Copilot at scale. In the Copilot Dashboard, analysts can understand how users perceive Copilot value by analysing the breakdown of thumbs up and thumbs down for Copilot responses, as well as see trends over time and breakdowns by group. This feature rolled out in March.

Admins can now use new metrics to better understand common user intents and usage patterns for Copilot across Microsoft 365 apps in the Copilot Dashboard and Advanced Analysis in Viva Insights. This feature is rolling out in April.

Copilot turning templates into Agent Builder

Copilot Tuning introduces new templates in Agent Builder designed for tasks such as drafting complex documents, validating documents against guidelines, and editing to match a distinct writing style. Users with Copilot Tuning enabled can further customise the template-based agents by tuning the context, tools, and underlying models with their organisation’s proprietary data, processes, and standards, empowering teams with customised agents aligned to how the organisation works. This feature will be available to enterprises with at least 5,000 Microsoft 365 Copilot licenses, will roll out to Frontier in April, and will roll out worldwide in June.
