01What Claude for Microsoft 365 Is and How It Works

Claude for Microsoft 365 is an integration that puts Claude inside Word, Excel, PowerPoint, and Outlook. It lets you work across all four apps at once, with Claude holding the full context of your project from one app to the next.

In this episode, Julian Goldie explains how Claude can read an email in Outlook, open the attachment in Word, build formulas in Excel, and create a PowerPoint deck—all without you copying and pasting between tabs. Claude carries the memory of what you're doing, so you don't have to repeat yourself.

The integration became generally available on May 7, 2026, for Word, Excel, and PowerPoint, with Outlook in public beta. It works by reading files that are currently open, and it can edit cells, slides, and text directly inside the apps. Every change is highlighted for your review before you save.

02Main Features of Claude for Microsoft 365

Here's what each app can do with Claude, as shown in the episode:

  • Claude for Excel: Reads your entire workbook—cells, formulas, tabs, comments. You can build a model from scratch, clean messy data, and test different assumptions. Claude edits cells directly and highlights every change for review.
  • Claude for PowerPoint: Reads your slide master, fonts, colors, and layouts. It builds slides that match your template and creates native PowerPoint charts you can edit later—not images.
  • Claude for Word: Reads your whole document, including tracked changes, comments, and footnotes. It can draft new sections in your heading style, fix tone, and redline contracts using tracked changes mode.
  • Claude for Outlook: In public beta. It can triage your inbox into three buckets: what needs your response, what Claude can draft, and what's noise. It drafts replies in your voice and reads attachments without opening them.

Claude can also summarize long email threads with citations, find meeting times across calendars, and draft calendar invites natively in Outlook.

03How to Set Up Claude for Microsoft 365

Getting started is simple, according to Julian. Follow these steps:

  1. Go to Microsoft AppSource and search for Claude.
  2. Install Claude for Excel, PowerPoint, and Word (one listing).
  3. Then install Claude for Outlook (a separate listing).
  4. Sign in with your Claude account. You need a paid plan (Claude Pro or higher); the free version doesn't include these add-ins.
  5. If you're on a Team or Enterprise plan, make sure your IT admin turns on cross-app working in the settings.

For larger companies, IT admins can deploy the add-in through the Microsoft 365 admin center. They can also use OpenTelemetry to monitor activity, and there's an analytics API for per-user usage. You can route through Amazon Bedrock, Google Cloud Vertex AI, or Microsoft Foundry if you already use those.

Once installed, just open Word, Excel, PowerPoint, or Outlook and start asking Claude questions. There's nothing new to learn.

04How to Use Claude for Microsoft 365: Examples

Julian walked through several real-world examples in the episode. Here are ways you can use Claude in your daily work:

  • Inbox triage: Open Outlook and ask, “What needs my attention today?” Claude reads your emails, tells you the ones that matter, and drafts replies for the easy ones. You spend 15 minutes on email instead of two hours.
  • Clean customer data: Open a messy spreadsheet of leads. Ask Claude to clean names, fix email formatting, and group people by city. It does it in one prompt.
  • Build a proposal: After a lead emails you, ask Claude to open the brief in Word, pull pricing from Excel, and make a deck in PowerPoint—all from one prompt, with all files aware of each other.
  • Turn a long email into a meeting: Ask Claude to summarize a 12-message thread, find a good time across calendars, and draft the invite. Done in 30 seconds.
  • Quarterly review prep: Update an Excel model, Word memo, and slide deck with new numbers. Change one assumption in Excel, and the deck and memo update too.

Claude can also turn a Word doc into a slide deck, redline a contract using tracked changes, and draft new sections in your heading style.

05Results and Comparisons Shown in the Episode

Julian didn't show specific test numbers, but he made direct comparisons between Claude and Microsoft's Copilot. He said most people who tried both for the same task preferred Claude because drafts feel more human, analysis feels deeper, and slides look cleaner.

He also highlighted the speed advantage: with Claude, a person can finish a proposal in 30 minutes, while someone without it might take four hours. Inbox triage can take 10 minutes instead of an hour each day.

Companies like ServiceNow are already using it. They report that Claude does the work in the app itself, rather than forcing users to move stuff between tools. That's the core value: less app switching, more work done inside the file.

06Tips, Limits, and Mistakes to Avoid

Julian shared some important limits to keep in mind:

  • Claude can only work with files that are currently open. It can't open or close files for you—you have to have the spreadsheet, deck, and doc open at the same time.
  • Chat history doesn't sync across devices because it's stored locally on your computer. If you start a chat on your laptop, you can't pick it up on your phone.
  • Cross-app chat history doesn't save between sessions. If you close everything and come back tomorrow, the history of how Claude worked across Excel and PowerPoint together is gone.
  • For Team and Enterprise plans, the org owner must turn on cross-app working first. If it's not working, ask your IT person to flip the toggle.
  • Don't try to use Claude for everything on day one. Start with one workflow you do every week—like a weekly report or clearing your inbox—and run it for a week to see the time saved.

Following these tips will help you avoid frustration and get the most out of the tool.

07Who Should Use Claude for Microsoft 365

Claude for Microsoft 365 is for anyone who lives in Microsoft Office: accountants, sales reps, office managers, lawyers—anyone who writes proposals, builds spreadsheets, or makes decks. If you're on Outlook all day, this will save you hours.

It's also for teams. If you manage a team that uses Microsoft 365, you can have IT deploy the add-in for everyone and monitor usage through the admin center.

But it's not for you if you only use Google Workspace. Claude has other tools like Claude for Chrome, but this update is specifically for Microsoft 365.

According to Julian, this is the update that finally breaks AI into normal businesses because the friction to start is zero. You don't learn a new app or change your workflow—Claude is just inside the apps you already use.

08Why This Update Matters and What to Do Next

Julian believes the gap between people using this and people not using it will grow huge fast. The person using Claude finishes proposals in 30 minutes, triages their inbox in 10 minutes, and the savings compound week after week.

If you're on a paid Claude plan, go to Microsoft AppSource and install the add-ins. If your team uses Microsoft 365, talk to your IT admin about deploying it and turning on cross-app working.

For a step-by-step playbook, Julian mentions the AI Profit Boardroom community, which has a 30-day roadmap for using Claude across Microsoft 365. It includes coaching calls, a prompt library, and a member map.
