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 although that connector gained write tools on July 7, 2026 for email, calendar, and OneDrive/SharePoint files, Teams specifically stays read-only. Claude can search your Teams messages (along with Outlook, SharePoint, and OneDrive), but it cannot post, reply, create, change, or send anything in Teams. And like every Claude connector, even that read-only search has no event triggers — nothing runs because a message was posted or you were @mentioned.
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 bridge across the Microsoft 365 suite, built on the Model Context Protocol (MCP) like the rest of the 400+ directory connectors.
The defining fact for Teams: even though the connector added write tools elsewhere in July 2026, Teams access stays 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 connector’s July 2026 write tools cover email, calendar, and OneDrive/SharePoint files — but not Teams, which remains read-only.)
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 has no event triggers. There’s no “when someone @mentions the team, summarize and route it” — nothing fires on a Teams event; the trigger is always you or a clock.
- Nothing watches the channel. Claude helps in the moment; it doesn’t follow a thread and act. The closest thing to “running on its own” is Claude Cowork’s scheduled tasks, which fire on a fixed clock, not on inbox events.
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 — the instant it’s said, and beyond what a read-only connector allows, you’ve crossed past what Claude offers here.
That’s where Carly fits. A customer escalation gets posted in a channel at 5:40pm on a Friday. Everyone’s seen it, nobody owns it, and it sits until Monday.
Carly is watching that channel. It reads the message, recognizes the account, pulls the open tickets and the last three emails from that customer, replies in the thread with who’s picking it up, and emails the customer an acknowledgment from your address before anyone has opened Teams.
Two more worth wiring:
- The @mention that needs a human. A message naming you in a channel you’ve muted gets triaged by urgency and either answered, or escalated to your phone with the context attached.
- The standup nobody writes. Yesterday’s channel activity, closed tickets, and merged PRs roll into a digest that posts itself, rather than into fifteen minutes of someone scrolling.
Carly fires on the event rather than on a clock, sends real email through Gmail and Outlook with attachments, and chains Teams into your calendar, CRM, and tasks as one flow. You set it up by describing it in plain English — it interviews you and builds it with you.
AI agents start at $35/month, and steps in a workflow that don’t use AI run free. 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 (native Teams integration) |
| Create or change anything | No (read-only) | Yes |
| Acts on triggers / events | No | Yes |
| Monitors channels on its own | No | Yes |
| Runs unattended on a schedule | Yes (Cowork tasks) | Yes |
| Sends email with attachments | Sends via M365 once an admin enables it, but not with attachments | Yes (Gmail + Outlook), with attachments |
| 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 Teams access is read-only. The connector’s July 2026 write tools cover email, calendar, and OneDrive/SharePoint files, not Teams. So 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 in Teams.
Can Claude post or reply in Microsoft Teams?
No. The connector’s write tools (added July 2026) don’t extend to Teams, which stays 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. For Teams the connector is read-only, and it has no event triggers — nothing fires because a message was posted or you were @mentioned. For that, Carly runs on the event itself.
Why is Teams read-only when the rest of the connector isn’t?
Anthropic’s July 2026 write tools deliberately exclude Teams — they added the ability to send email, manage calendar events, and create and update OneDrive/SharePoint files, but Teams stays search-and-read only. See Claude for Microsoft 365 for the full picture. For posting in Teams 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."
