Claude for Microsoft 365 (Excel, PowerPoint, Word GA; Outlook Beta)

Claude's add-ins for Excel, PowerPoint, and Word are generally available on all paid plans and now share full context across the three apps. Plus a new Outlook add-in launches in public beta.

Details

Excel, PowerPoint, and Word add-ins are out of beta on all paid plans (Pro, Max, Team, Enterprise)
The three GA add-ins share full conversation context, so Claude carries what it knows from one app into the next
Outlook add-in is in public beta on all paid plans: triages unread mail, drafts replies/forwards in your voice (learned from your sent folder), summarizes threads with citations, reads docx/xlsx/pptx/pdf attachments inline, and finds meeting times
Outlook drafts land unsent in the native compose pane; you still click send (no programmatic Mail.Send during beta)
