Collaborate with Claude across Excel, PowerPoint, Word and Outlook
One conversation that carries context across all four apps
Starting today, Claude for Excel, PowerPoint, and Word are generally available, and Claude for Outlook is now in public beta for all paid plans. As Claude moves between tasks in your Microsoft apps, it keeps the full context of your conversation.
One conversation across four apps
Most work doesn't live in one application, so Claude moves between them as you do. Triage an email in Outlook, open the attachment in Word to draft a memo in your team's template, build the supporting analysis in Excel, and turn it into a deck in PowerPoint — all without re-explaining what you're working on. Adjust an assumption in Excel and the chart in PowerPoint and the number in your Word memo automatically update, too.
Claude works across open files, so keep the spreadsheet, deck, and memo open side by side and changes will flow between them.
Conversations persist with each file, so you can close the sidebar, reopen it the next day, and pick up where you left off using your keyboard or your voice.
Claude for Outlook
Claude for Outlook brings Claude into your inbox. Ask Claude to triage your inbox and it sorts messages by what needs your response, what it can draft for you, and what's noise. Replies land as drafts in Outlook's compose pane with recipients, subject, and body filled in. Calendar invites check attendee availability and open in Outlook's native event form.
Open an attachment in Word or Excel and Claude already knows what the sender asked for. You review every reply and calendar invite before it goes out, and nothing goes out until you click send.
Deploying Claude for Microsoft 365 across your organization
Claude for Excel, PowerPoint, and Word are now generally available, with the controls IT admins and organizations need. One AppSource listing covers Excel, PowerPoint, and Word, and a separate listing adds Outlook in beta. Admins can deploy both from the Microsoft admin center.
Enterprise admins can configure OpenTelemetry to stream prompts, tool calls, and document references to their own collector, so security teams see exactly what Claude does across every app. The Analytics API breaks out activity per user, per app, per day.
Organizations can access all four add-ins with a Claude account, or route traffic through an existing LLM gateway to Claude models running on Amazon Bedrock, Google Cloud’s Vertex AI, or Microsoft Foundry.
Microsoft 365 Copilot customers can also work with Claude AI models directly within Excel and PowerPoint.
How organizations use Claude for Microsoft 365
“We can instruct Claude to build a style guide from an executive's prior written communications so our EAs can draft their emails in their voice. That's high-leverage work the team would never have time to set up by hand.”
“Claude for M365 is being rapidly adopted by ServiceNow. Claude does the work in Excel itself, instead of asking us to move content between tools, driving step change in productivity.”
“Our investment professionals live in data and analytical models, and Claude for Excel meets them there. Analysts are using it to build and update coverage models, separate signal from noise, and pressure-test their work — all with a step-change in efficiency.”
“Claude in Excel allows my teams to build an initial version of complex models faster, enabling them to focus on refining the model, pressure testing inputs and assumption, and exploring more scenarios and trade-offs. This helps us have richer and deeper discussions with our clients earlier.”
“Claude enables a seamless transition from rough ideas to polished, branded deliverables across presentation, document and spreadsheet applications without disrupting the workflow. That end-to-end consistency has been a significant time-saver, especially when quality, formatting, and speed all matter.”
