Claude brings cross-app workflows to Microsoft 365

Anthropic says Claude for Excel, PowerPoint and Word is generally available, while Claude for Outlook is in public beta for all paid plans.[1] The paid plans listed in the evidence are Pro, Max, Team and Enterprise.[2] In Excel, Claude can answer questions about cells, update assumptions without breaking formulas and build models from scratch.[3] In PowerPoint, it can build slides in a user’s template, edit selected content, and generate native charts and diagrams.[3] In Word, it supports tracked changes, comment-thread replies and updates using company styles.[3]

Anthropic says Claude can read from one Microsoft 365 app and make changes in another within one conversation, carrying conversation context between tasks.[1][2] It can pass changes among open spreadsheets, presentations and documents; for example, changing an Excel assumption can update a PowerPoint chart and the corresponding number in a Word memo.[1] Conversations persist with each file, so users can resume later by keyboard or voice.[1] The important boundary is that Claude can only read and write files and Outlook items that are currently open.[2]

Claude for Outlook can sort inbox messages into those needing a response, those for which it can draft a reply, and noise, according to Anthropic.[1] Prepared replies have the recipients, subject and body filled in.[1] For calendar invites, Anthropic says Claude checks attendee availability and opens the invite in Outlook’s native event form.[1] Users must review replies and invites, and nothing is sent until they click send.[1] Anthropic also says Claude carries the sender’s request context when a user opens an email attachment in Word or Excel.[1]

Anthropic says one AppSource listing covers Excel, PowerPoint and Word, while a separate beta listing adds Outlook; admins can deploy both through Microsoft’s admin center.[1] Enterprise admins can configure OpenTelemetry to stream prompts, tool calls and document references to their own collector, and the Analytics API breaks out activity by user, app and day.[1] Organizations can use a Claude account or route traffic through an existing LLM gateway to Claude models on Amazon Bedrock, Google Cloud Vertex AI or Microsoft Foundry.[1] Microsoft 365 Copilot customers can use Claude AI models directly in Excel and PowerPoint.[1]
