Over MCP there is no trusted place to confirm a write in the moment, so the consent screen is the standing approval rather than a formality. Grant Read and Run tools. Think hard before granting Delete, which reaches into connected apps and cannot be undone. ## What teams do with Outlook Calendar through Elaichi ### Book the follow-up before the call ends Sales. Ask for the next open half hour that works for you and the prospect, and have the event created in Outlook Calendar with the right attendees and a note on what was agreed. ### Find a slot that works for everyone Executive assistants. Check free and busy times across a group of colleagues in one question instead of opening each calendar, then put the meeting on everyone's Outlook Calendar. ### Schedule interview panels without the back and forth Recruiting. See when each interviewer is free, create the panel events in Outlook Calendar, and move them when a candidate asks for a different day. ### Move a customer callback when plans change Support. When a customer reschedules, have the existing Outlook Calendar event updated with the new time and attendees rather than creating a duplicate and leaving the old one in place. ### Prepare for tomorrow's meetings in one pass Customer success. Pull up tomorrow's events from Outlook Calendar, including who is attending and what attachments were shared, and get a short brief for each one before the day starts. ### Clean up recurring meetings that have gone stale Operations. List the upcoming instances of a recurring Outlook Calendar meeting, spot the ones nobody needs anymore, and cancel them so rooms and afternoons are freed up. ## Frequently asked questions ### How do I connect Outlook Calendar to Claude? First, open Elaichi, choose Outlook Calendar, and sign in with your Microsoft account when the familiar Microsoft sign-in window appears; Outlook Calendar connects over OAuth, so there is no OAuth application to register and no client ID or secret to generate. Then, in Claude, go to Customize, then Connectors, then Add, and paste https://api.elaichi.ai/mcp as the address. Claude will ask you to sign in to Elaichi, and from then on it can work with your Outlook Calendar events. ### Does Outlook Calendar work with ChatGPT and Cursor as well as Claude? Yes. Once Outlook Calendar is connected in Elaichi, the same endpoint, https://api.elaichi.ai/mcp, works in Claude, ChatGPT, Cursor, any other MCP client, and the Elaichi Agent. You connect Outlook Calendar once and every client you use picks it up. ### What can an AI agent actually do with my Outlook Calendar data? An agent can list your Outlook Calendar calendars and the events on them, open a single event to see its attendees and attachments, and check free and busy times for you and your colleagues. It can create new events, update the time, title, or attendee list of existing ones, cancel events, and look through the instances of a recurring meeting. It can also look up people and users in your organization so it invites the right person. ### Does connecting Outlook Calendar give the AI access to every calendar in my organization? No. An agent working through Outlook Calendar sees only what the person who signed in can already see, so calendars that have not been shared with you stay out of reach. Elaichi can narrow that access further, for example to reading events but not changing them, and it never widens it beyond what your Microsoft account allows. ### Can my team share one Outlook Calendar connection? Yes. One person connects Outlook Calendar in Elaichi and shares the connection with a team, and nobody else on the team ever handles a password or credential. Each teammate still signs in to Elaichi as themselves, so every event created or moved through the shared Outlook Calendar connection is logged with the name of the person who did it. ### Can I stop an agent from deleting or changing events in Outlook Calendar? Yes. In Elaichi you can restrict Outlook Calendar action by action, so an agent might be allowed to read events and check availability but not create, update, or cancel anything. A blocked action is never advertised to Claude, ChatGPT, Cursor, or any other client, so no prompt, however worded, can reach it. ### What happens to an Outlook Calendar connection when someone leaves the company? When you offboard someone in Elaichi, their access to Outlook Calendar through every AI client ends at once. If they had shared their Outlook Calendar connection with a team, an administrator can keep it working for everyone else or replace it. Disconnecting Outlook Calendar once in Elaichi removes it from Claude, ChatGPT, Cursor, and every other client at the same time. ## All 17 Outlook Calendar tools Every tool below is callable through https://api.elaichi.ai/mcp once Outlook Calendar is connected, subject to the toolbox it is in and the restrictions on the caller. - **List all Outlook Calendar me** (List).
