Connecting Outlook to an Autonomous AI Agent
Outlook is where professional email and calendars concentrate. The Outlook connector is coming soon: an Atako agent will be able to sort messages, prepare replies and organize appointments, without ever seeing your Microsoft password.

Possible workflows
Sorting and reply drafts for the shared inbox
A support@ or contact@ inbox receives dozens of messages a day. The agent will list unread messages with list_messages, sort them by category with add_category_to_message (billing, bug, general question), then draft a reply with create_draft for every clear request. A human will review it and send it with send_draft. The agent will only use send_email if it has been given that specific grant.
Automatic appointment scheduling from an incoming email request
A customer asks for a meeting by email. The agent will retrieve the request with get_message, check free slots with check_availability, create the event with create_event once a slot is chosen, then prepare a confirmation reply with create_draft. The appointment will only appear on the calendar if the create_event grant has been given, and the reply will only go out after human review, unless send_draft or send_email has been explicitly authorized.
Calendar cleanup and conflict alerts
The agent will list upcoming events with list_events, spot overlaps between two meetings or an appointment left unconfirmed, and prepare a cancellation with cancel_event only if that grant has been given. Without it, it will flag the conflict in a draft addressed to the organizer with create_draft, so a human can decide.

Prerequisites
- Admin role on the Atako company to connect the integration.
- A personal Microsoft account or a Microsoft 365 work account whose mailbox and calendar need to be connected.
- Microsoft OAuth consent, scopes Mail.ReadWrite, Mail.Send, and Calendars.ReadWrite.
- An explicit grant per agent, especially for the send_email and create_event actions.
How to connect
- 1
Open Context, Integrations
Once the connector is live, an admin will select Outlook from the list of connectors.
- 2
Review the exposed actions
The window will show every mail and calendar action, read and write, before authorization.
- 3
Authenticate through the Microsoft screen
Redirect to Microsoft consent; no password will be sent to Atako.
- 4
Grant access to an agent
You will choose the precise actions per agent, for example create_draft and check_availability alone to stay cautious.
Why Connect an Autonomous Agent to Outlook
The Outlook connector is not available yet. This page describes what it will do once it is live.
Outlook is where both email and the calendar concentrate for a large share of companies, especially those on Microsoft 365. An autonomous agent connected to it won't just respond to a single command: it will run continuously and decide, depending on the instruction it receives, to search for a message, check a free slot or prepare an appointment, through tool calling.
The connection will use OAuth 2.0 and the Microsoft Graph scopes Mail.ReadWrite, Mail.Send and Calendars.ReadWrite (Microsoft Graph permissions reference). These scopes allow reading, composing and sending emails, and managing calendar events, never deleting an account or changing security settings.
That's what will make a workflow like scheduling an appointment from an incoming email useful, close to what a support triage or support automation agent does: it will receive a request and prepare the next step (a slot, a confirmation draft) without waiting for a human to open their calendar to check availability. Outlook will be one of the integrations covered by the Standard plan, with no separate billing line per connector.
Limits and Best Practices
The connector's most sensitive actions will be send_email and create_event: once granted with write scope, the agent will send an email or book an appointment without checking back with you. The safest practice will be to grant only create_draft and check_availability: the agent prepares, a human validates.
The Mail.ReadWrite and Calendars.ReadWrite scopes cover the entire connected mailbox and calendar, not one specific folder or calendar. The real limit will therefore come from the grant: list the exact actions the agent needs rather than granting everything at once when you connect.
Every call, whether sent or refused, will be visible in the agent page's audit log. As with any OAuth account, if the token expires or is revoked on the Microsoft side, the connection will switch to error status until it's reconnected.

Frequently asked questions
Will the agent be able to send an email or create an appointment without validation?+
Only if the grant includes send_email or create_event with write scope; the agent will then act directly. Granting only create_draft and check_availability keeps a human in the loop: the agent prepares, a human reviews and sends, or confirms the proposed appointment.
Will Outlook be included in the Standard plan?+
Yes. Like every integration, Outlook will be included in the Standard plan, with no extra cost per connector.
How will I revoke Atako's access to my Outlook mailbox and calendar?+
From Context, Integrations, with Revoke on the Outlook connection. The encrypted token will be deleted immediately, and every agent using it will lose access at once.
Will the Calendars.ReadWrite scope let the agent see colleagues' calendars?+
No. This scope only covers the connected Microsoft account. The agent will only see a colleague's calendar if it has been explicitly shared with that account beforehand, independently of the connector.
