Outlook MCP: connect Outlook to Claude and ChatGPT
Ask Claude or ChatGPT what the customer wrote about the renewal, what your Thursday looks like, or to draft a reply to the board invite. The answer comes from your own Outlook mail and calendar, with a link back to the message or event.
With Deployed OS everyone connects their own Microsoft 365 work account. Drafts wait in Drafts and new events go on your own calendar. Nothing is sent and nobody is invited.

Who sees what
- What it reads and writes
- The connector searches and reads your own mail and calendar, creates plain-text drafts and adds events to your own calendar. It cannot send mail, invite anyone, or change or delete existing messages and events.
- Each person’s own account
- Everyone connects their own Microsoft 365 work account, so the AI sees that person’s mailbox and calendar and nobody else’s.
- You choose who gets it
- Admins decide which groups at the company get Outlook mail and calendar, and which of them may also create drafts and events. Everyone else never sees them.
- Every call logged
- Who read, who drafted, who booked, when. Deployed OS shows reads and writes per connector and per person, the log can be exported, and access is revoked centrally the day someone leaves.
Set up the Outlook connector in three steps
Outlook’s own MCP server or Deployed OS?
Microsoft publishes its own MCP servers for Outlook mail and calendar under Work IQ, in preview. They are part of Microsoft Agent 365 and suit a team building agents on Microsoft’s platform.
Deployed OS is one company connection for Outlook and the rest of your tools, with each person’s own login, admins choosing which groups get what, and a log of every call. The same connection works in Claude, ChatGPT and Copilot, next to your company’s skills and guardrails.
Outlook MCP: common questions
Yes. Microsoft publishes Work IQ MCP servers for Outlook mail and calendar, in preview. Deployed OS gives the whole company one connection to Outlook and your other tools, with each person’s own login, access per group and a log of every call.
No. It reads mail and calendar, saves drafts in your Drafts folder and adds events to your own calendar. Microsoft emails every attendee of a new event, so proposed attendees go in the event text and you invite them from Outlook. If you want it to do more, we can extend it for you.
Yes, and a ChatGPT and Copilot one too. Deployed OS is your company’s own Outlook MCP server, so the same connection works in all three. People keep the assistant they prefer.
For the first step, yes. Someone who may register applications in Microsoft Entra ID creates the app registration. Granting admin consent for the company spares each person a consent prompt when they connect. We walk you through it.
Not today. The connector works on each person’s own mailbox and calendar. If you need shared mailboxes, we can extend it for you.
It depends on the size of your team. Get in touch and we will walk you through it.
