# How to integrate Microsoft Outlook with your AI Agents and what the integration can be used for

This guide provides step-by-step instructions for integrating Microsoft Outlook with your AI Agents and how you can use the feature.

## What is Microsoft Outlook?

Microsoft Outlook allows AI Agents to work with your mailbox and calendar so they can help you read, organise, draft, and send emails, as well as create and manage calendar events.

## Key Microsoft Outlook features

- Retrieve email lists from your mailbox to help you prioritise what to read next.
- Pull full email content including message body so an AI Agent can summarise and classify messages.
- Retrieve full conversation threads so you can see context before replying.
- Draft emails for review before sending, keeping a human in the loop.
- Send emails when you explicitly instruct the AI Agent to send .
- Add attachments to emails typically to drafts .
- List mail folders so an AI Agent can work with Inbox/Drafts/Sent Items and other folders.
- Categorise emails using Outlook categories to support triage and workflows.
- Create, update, list, and delete calendar events including recurring event instances via calendar view .
- Optionally create online meetings for events where supported by your Outlook setup .
## Example Microsoft Outlook use cases

- Automatically summarise your most recent emails each morning and highlight which ones look urgent or time-sensitive.
- Draft replies to customer queries and queue them in Drafts for a manager to approve and send.
- Pull an entire email thread, extract decisions and action items, then log them into your task system.
- Create calendar events from a message for example, “Book a 30-minute follow-up next week with these attendees” .

1. Select Microsoft Outlook from the available integrations list.
1. Click Connect and complete the Microsoft sign-in flow.

1. If your organisation uses Microsoft 365 with IT controls, ask your IT admin to approve the connected app if prompted.
1. Return to your AI Agent and run a simple validation test:
  1. Ask the agent to list recent emails subjects only .
  1. Ask the agent to retrieve one email’s body.
  1. Ask the agent to create a draft email do not send yet .
1. Optional but recommended Decide your “human in the loop” policy:
- Draft-only mode for most users.
- Send-enabled mode only for approved agents and approved users.
## How to use Microsoft Outlook and your AI Agents

- Build an “Inbox triage” workflow:
  - Ask the agent to fetch the latest emails.

  - Ask it to summarise the thread and extract next steps.
  - Ask it to draft a reply that addresses the latest open questions.
- Run a “Draft then send” workflow for outbound updates:
  - Ask the agent to draft an email to a recipient with a specific subject and content.
  - Review the draft content.
  - Instruct the agent to send the draft only when you are happy.
- Manage calendar support:
  - Ask the agent to list events within a date range.

## Best practices for Microsoft Outlook and your AI Agents

- Use draft-first workflows for most scenarios, and only enable sending when there is a clear business need.
- Ask the AI Agent to summarise threads before drafting replies so responses stay consistent with the full context.
- Use categories to implement a simple triage system for example: urgent, awaiting reply, delegated, follow-up .
- Standardise how you want subject lines written so outbound emails are easy to search later.
- For recurring tasks, ask the agent to produce a daily or weekly email summary at a consistent time.
- When creating meetings, include agenda, desired outcome, and required attendees in the instruction so calendar events are consistently useful.
## Troubleshooting & common issues

|  | Cause | Issue | Solution |
|  | Insufficient permissions granted during connection, or the connected account lacks access to the mailbox | Emails can be listed, but the AI Agent cannot fetch the full message body | Reconnect Microsoft Outlook and re-approve permissions, then re-test by retrieving a single message with full details |
|  | The AI Agent has not been granted permission to send, or sending is restricted by organisational policies | Draft creation works, but sending fails | Use a draft-first workflow and keep a human approval step; if sending is required, request the appropriate permission or IT approval, then test by sending to an internal address |
|  | The message is part of a larger conversation and the agent is only pulling a single message rather than the whole conversation | Threads are incomplete or replies are missing | Ask the agent to retrieve messages by conversation/thread and then summarise the full thread before drafting a response |
## FAQs

Q: Can my AI Agent send an email without me asking it to?

A: It will only send emails if you explicitly instruct it to send and the agent is configured with sending permissions. If you want to enforce human oversight, use draft-first workflows and only allow sending after approval.

Q: Can the AI Agent help me decide which emails are urgent?

A: Yes. Once the agent can access message content, you can instruct it to review messages for urgency signals deadlines, escalations, sentiment, key customers and then produce a prioritised list with recommended next actions.

Q: Can my AI Agent manage my calendar as well as email?

A: Yes, if your Outlook calendar features are enabled in the integration. You can instruct the agent to list events in a date range, create meetings with attendees and an agenda, and update or cancel events when needed.
