Microsoft Copilot Health Is Now in Preview for U.S. Microsoft 365 Subscribers
Copilot Health entered public preview on May 29, 2026, giving eligible U.S. Microsoft 365 subscribers AI-powered health insights, wearable data, and EHR access.
Microsoft already fields more than 50 million health-related questions a day across its consumer products. On May 29, 2026, it took that a step further by opening Copilot Health to a broader preview audience in the United States, giving eligible Microsoft 365 subscribers a dedicated space to bring their health data together and get personalised guidance from an AI that actually knows their context.
Who Can Access It
Copilot Health is available in preview to anyone aged 18 or over in the US with a Microsoft 365 Personal, Family, or Premium subscription. You access it at copilot.microsoft.com/health. Work or school accounts are not eligible, and the feature is currently English-only. Microsoft has not announced a timeline for expanding to other countries or languages, though a broader rollout is tentatively expected in late 2026.
If you have a qualifying subscription, it is worth checking your access now. The rollout is phased, so not everyone will see it on day one.
What Copilot Health Actually Does
The core idea is straightforward: rather than asking a general-purpose AI a health question with zero context, Copilot Health lets you build a health profile and connect your data, so the responses it gives are grounded in your actual situation.
Here is what you can connect:
- Wearable devices and wellness apps. The integration starts with Apple Health and covers over 50 devices including Oura and Fitbit, with more being added. Activity levels, sleep patterns, vital signs, and other trends all flow in.
- Electronic health records. Via a provider called HealthEx, Copilot Health can pull records from over 50,000 US hospitals and provider organisations, including visit summaries, medication lists, and test results. The underlying infrastructure uses FHIR-endpoint exchange and TEFCA individual access services.
- Lab results. Comprehensive lab test results come through a partner called Function.
Once your data is connected, Copilot Health can help you understand trends, prepare for appointments, and make sense of results that might otherwise sit unread in a patient portal.
The Guidance Layer
Beyond showing you your data, Copilot Health is designed to answer follow-up questions and help you work out what to do next. Its responses draw on guidance from thousands of trusted health organisations globally, sourced using principles published by the National Academy of Medicine and through a partnership with Harvard Health.
If the conversation points toward needing in-person care, you can search for local healthcare providers filtered by specialty, language, gender, insurance, and location directly within the tool.
It is worth being clear about what this is not. Copilot Health is not a medical device. It cannot diagnose, treat, or prevent conditions, and it is not a substitute for professional medical advice. Think of it as a well-informed starting point, not a replacement for a clinician.
The Privacy Setup
Health data is sensitive, and Microsoft has been explicit about how it handles it. A few things worth knowing:
- Copilot Health conversations are kept separate from the rest of Copilot and are not used to train AI models.
- Your health data sits in an encrypted partition that does not mix with your Bing search history, advertising profile, or any other Microsoft Graph data.
- You can manage, delete, or disconnect any health data source at any time.
- The service has achieved ISO/IEC 42001 certification, an independently verified standard for AI management systems.
That last point matters. It means a third party has assessed how Microsoft builds and governs the AI behind this service, not just how it markets it.
How It Was Built
Copilot Health was developed with an internal clinical team and informed by an external panel of over 250 physicians from more than 24 countries. Safety guardrails were co-developed across responsible AI, clinical, safety, engineering, and health product teams specifically to protect against health misinformation while also accounting for emotional wellbeing.
The underlying AI work draws on research including the Microsoft AI Diagnostic Orchestrator (MAI-DxO), which has shown strong results in research settings combining broad general medicine knowledge with specialist-level depth. Copilot Health as a consumer product is not at that level yet, but this is the direction of travel.
The Bigger Picture
Microsoft first announced Copilot Health in March 2026 and opened a waitlist to begin testing. This preview is the next stage, expanding access significantly after months of internal and limited external evaluation.
It sits alongside moves from OpenAI (ChatGPT Health, January 2026) and Anthropic (Claude for Healthcare, also January 2026), making the first half of 2026 a notable moment for consumer health AI broadly. Microsoft’s approach of bundling Copilot Health with an existing subscription rather than pricing it separately lowers the barrier considerably for the tens of millions of people already paying for Microsoft 365.
What This Means for You
If you are a Microsoft 365 subscriber in the US, this is worth trying. The combination of wearable data, real health records, and AI that can ask sensible follow-up questions is genuinely more useful than a generic chatbot search. Being able to walk into a GP appointment having already made sense of your recent blood work or sleep data has practical value.
The privacy architecture is thoughtful, the clinical input is real, and the third-party certification adds meaningful accountability. The usual caveats apply during any preview period: features may change, usage limits may vary, and this is not a finished product.
For now, if you qualify, head to copilot.microsoft.com/health and see what it can do with your data.
