Claude for Microsoft 365 is now generally available for Word, Excel, and PowerPoint — and Outlook has entered public beta. Here's exactly how to get it installed and running in under five minutes. ## Prerequisites Before you start, confirm you have: - An active Microsoft 365 subscription (any tier that includes Word, Excel, and PowerPoint) - An active **Anthropic Claude subscription** — Pro, Team, or Enterprise plan (free Claude accounts are not supported for the Office add-in integration) - Administrator rights may be required if you're on a managed corporate machine — check with your IT department if you're unsure ## Option A: Install from Inside an Office App This is the quickest route and works inside any of the three supported apps. 1. Open **Word**, **Excel**, or **PowerPoint** (any of the three) 2. In the top ribbon, click **Insert** 3. Select **Add-ins** → **Get Add-ins** 4. In the Office Add-ins dialog that opens, use the search bar to search for **Claude** 5. Find the official Anthropic Claude add-in (verify the publisher is Anthropic) 6. Click **Add** 7. Accept the permissions prompt if one appears 8. Sign in with your Anthropic account when prompted The add-in installs once and will be available across Word, Excel, and PowerPoint — you don't need to repeat this process for each app separately. ## Option B: Install from Microsoft AppSource in Your Browser If you prefer to browse before installing, or if the in-app store is restricted on your device: 1. Open your browser and navigate to [appsource.microsoft.com](https://appsource.microsoft.com) 2. Search for **"Claude"** using the search bar at the top 3. Locate the official Anthropic Claude for Microsoft 365 listing 4. Click **Get it now** and follow the prompts to associate the add-in with your Microsoft 365 account 5. Open Word, Excel, or PowerPoint — the Claude panel should appear in your ribbon ## After Installation: Finding the Claude Panel Once installed, Claude shows up as a side panel in each supported app. Look for: - A **Claude button** in the ribbon (usually under the Home or Insert tab, depending on your version) - Or a **Claude icon** in the right-side panel area Click it to open the chat interface. On first launch you'll be prompted to authenticate with your Anthropic account credentials. ## The Key Feature: Cross-App Context Here's what makes this more than just a chatbot in a side panel. **Claude remembers your conversation as you move between apps.** Practical workflow example: 1. In **Outlook** (beta): "Summarize the last week of emails from the Project Alpha thread" 2. Switch to **Word**: Claude still has the context of that summary — "Now draft a status memo based on those emails" 3. Switch to **PowerPoint**: "Build a 5-slide deck structure from the key points in that memo" You don't need to re-paste content or re-explain what you're working on. Claude carries the full conversation context across the apps. ## What Each App Can Do **Word:** - Draft new documents from a brief - Rewrite or improve existing paragraphs - Summarize long documents - Adjust tone (formal, casual, technical) - Format and restructure content **Excel:** - Build and explain formulas - Edit cells and update assumptions - Work across multiple tabs without breaking existing formulas - Summarize or analyze data ranges - Generate charts and table explanations **PowerPoint:** - Create slide outlines from a topic or document - Write speaker notes - Suggest visual structure for a presentation - Summarize or compress existing slide decks **Outlook (Beta):** - Draft replies to emails - Summarize long email threads - Compose new emails from a brief - Adjust the tone of a drafted reply ## Subscription Requirement Details The add-in requires an active paid Anthropic plan: - **Claude Pro** — individual subscription, suitable for personal use - **Claude Team** — for small teams with shared management - **Claude Enterprise** — for organization-wide deployment with SSO and admin controls If you're evaluating this for enterprise deployment, the Enterprise plan also enables IT admin controls over the add-in, including centralized installation across a Microsoft 365 tenant. > **Note:** Your Microsoft 365 subscription tier is separate from your Anthropic subscription. You pay for both independently. A Microsoft 365 Business Basic subscription alone does not include Claude access. ## Troubleshooting **Add-in not appearing after install:** Close and reopen the Office app. Add-ins sometimes require a restart to appear in the ribbon. **"Sign in" loop or authentication failure:** Ensure your Anthropic account has an active Pro, Team, or Enterprise subscription. Free accounts will not authenticate successfully. **Restricted by IT policy:** Your IT administrator may need to whitelist the add-in through the Microsoft 365 admin center at [admin.microsoft.com](https://admin.microsoft.com). Ask them to enable the Anthropic Claude add-in under the add-in management settings. **Cross-app context not working:** Ensure you're signed into the same Anthropic account in each app session. Context is tied to your authenticated session — signing into different accounts across apps will break continuity. --- ## Sources 1.
