Claude + Microsoft Teams: What the Integration Can (and Can't) Do in 2026
Claude can read Microsoft Teams — but it can’t act in it. Teams is reached through Claude’s Microsoft 365 connector, and Anthropic states that connector is read-only. Claude can search your Teams messages (along with Outlook, SharePoint, and OneDrive), but it cannot post, reply, create, change, or send anything. And like every Claude connector, even that read-only search only works inside a chat you start — there are no triggers, and nothing runs while you’re away.
Here’s exactly how the connection works, how to turn it on, where the limits bite, and what to use if you want Teams work that runs on its own.
How Claude connects to Microsoft Teams
There’s no standalone Teams app in Anthropic’s Connectors Directory. Teams comes bundled into the Microsoft 365 connector — Anthropic’s single read-only bridge across the Microsoft 365 suite, built on the Model Context Protocol (MCP) like the rest of the 400+ directory connectors.
The defining fact is right there in how Anthropic describes it: the Microsoft 365 connector is read-only. Through it, Claude can:
- Search Teams messages — find a discussion or decision across channels and chats.
- Search Outlook, SharePoint, and OneDrive — pull email and documents in as context too.
What it cannot do is just as important:
- No posting or replying in Teams.
- No creating, editing, or deleting messages or channels.
- No sending anything — the same read-only limit that applies across the 365 connector.
So Claude treats Teams as a searchable archive to read from, not a place it can act. (For the broader picture of this connector, see Claude for Microsoft 365.)
How to set it up
Setup lives in Claude’s connector settings:
- Open Settings → Connectors in the Claude app or on claude.ai.
- Find the Microsoft 365 connector and click Connect.
- Sign in with your Microsoft account and approve the requested permissions (your tenant admin may need to allow it).
- Back in a chat, ask Claude to find something in Teams — it’ll search through the read-only connector.
The first-party directory connectors are available broadly; custom connectors (your own MCP server) require a paid plan. Note that connecting won’t unlock posting or sending — the read-only limit stands regardless of plan.
The limits that actually matter
The read-only nature is the whole story. The integration’s shape is “a search box over your Microsoft 365,” not “an agent that works in Teams.” Three limits define it:
- Read-only, full stop. Claude can search Teams messages but can’t post, reply, create, change, or send. There’s no “reply in this channel” or “message the team.”
- No triggers, no automation. Even the read access only works inside a conversation you start. There’s no “when someone @mentions the team, summarize and route it” — nothing fires on a Teams event; you have to be in the chat, prompting.
- Conversation-only and laptop-bound for scheduled work. Claude helps in the moment; it doesn’t watch channels and act. The closest thing to “running on its own” is Claude Cowork’s scheduled tasks, which fire on a fixed clock and only “while your computer is awake and the Claude Desktop app is open.”
So Claude is great for “find what was decided in Teams last week” and not built for “watch these channels and respond when something happens.”
If you want Microsoft Teams work that runs on its own: Carly
The moment you want something to actually happen in Teams — or anywhere — without you in the chat, and beyond what a read-only connector allows, you’ve crossed past what Claude offers here.
That’s where Carly fits. Carly is an AI executive assistant built to act on triggers, not just search in a chat:
- Fires on events, 24/7, in the cloud — when something happens, Carly acts; your laptop doesn’t need to be awake.
- Connects Teams into the rest of your stack — route messages and tie them to email, calendar, CRM, and tasks as part of a workflow.
- Actually sends and updates — drafts and sends email (Gmail and Outlook) with attachments, files and labels, manages tasks, updates your CRM, and records meetings — the actions a read-only connector can’t touch.
- Builds the workflow for you — tell it “I’d like to set up a system that flags urgent Teams messages and follows up by email” in plain English; it interviews you, then builds it with you. No prompt engineering.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free and unlimited. Carly connects to 200+ tools across 40+ categories — see integrations and the Microsoft Teams integration page.
Claude’s Microsoft Teams integration vs Carly
| Claude (Microsoft 365 connector) | Carly | |
|---|---|---|
| Search Teams messages | Yes (read-only) | Yes |
| Post / reply in Teams | No (read-only) | Yes |
| Create or change anything | No (read-only) | Yes |
| Acts on triggers / events | No | Yes |
| Monitors channels on its own | No | Yes |
| Works while laptop is closed | No | Yes (cloud) |
| Sends email with attachments | No (Gmail draft-only) | Yes (Gmail + Outlook) |
| Pricing | Free broadly, but read-only | AI agents from $35/mo |
Claude’s connector is a strong Teams search tool inside a chat. Carly is a teammate that acts across Teams, email, and the rest of your stack.
Frequently Asked Questions
Does Claude integrate with Microsoft Teams?
Yes, through the Microsoft 365 connector — but Anthropic states it’s read-only. Claude can search your Teams messages (plus Outlook, SharePoint, and OneDrive) inside a chat, but it can’t post, reply, create, change, or send anything.
Can Claude post or reply in Microsoft Teams?
No. The Microsoft 365 connector is read-only, so Claude can search Teams messages but cannot post, reply, or change anything. For posting and acting in Teams workflows, you need an agent platform like Carly.
How do I connect Claude to Microsoft Teams?
Go to Settings → Connectors in the Claude app or on claude.ai, connect the Microsoft 365 connector, sign in with your Microsoft account, and approve permissions (your admin may need to allow it). Then ask Claude to search Teams in a chat.
Can Claude monitor Teams and act when something happens?
No. The connector is read-only and only works inside a conversation you start — there are no event triggers. For automatic, trigger-based Teams workflows, Carly fires on events 24/7 in the cloud.
Why is the Microsoft 365 connector read-only?
That’s how Anthropic ships it — the connector is for searching across Teams, Outlook, SharePoint, and OneDrive, not for taking actions. See Claude for Microsoft 365 for the full picture. For sending and acting across both Microsoft and Google, Carly handles the write side.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
