As of July 2026 there is no first-party Claude bot or app for Microsoft Teams - Anthropic ships Claude for Excel, Word, PowerPoint and Outlook, and a Microsoft 365 connector, but nothing you can @mention in a Teams channel. The connector is genuinely useful and often mistaken for a bot: from claude.ai, Claude can search your Teams chats and read your calendar, alongside SharePoint, OneDrive and Outlook. What it cannot do is write - Anthropic's own documentation states plainly that Claude cannot send Teams messages. Anthropic has said it wants to bring Claude Tag to Teams and is running a waitlist, but has given no date. So the paths are: use the connector and accept read-only, build your own Teams agent on the Microsoft 365 Agents SDK, or adopt a product that already lives in Teams.
