# Microsoft Outlook Trigger

Learn how to use the Microsoft Outlook Trigger node in n8n. Follow technical documentation to integrate Microsoft Outlook Trigger node into your workflows.

Use the Microsoft Outlook Trigger node to respond to events in [Microsoft Outlook](https://www.microsoft.com/en-us/microsoft-365/outlook/email-and-calendar-software-microsoft-outlook) and integrate Microsoft Outlook with other applications.

On this page, you'll find a list of events the Microsoft Outlook Trigger node can respond to, and links to more resources.

**Credentials**

This node's **Authentication** dropdown offers three options:

* **Outlook OAuth2**: the Microsoft Outlook-specific OAuth2 credential (default).
* **Microsoft OAuth2 (Graph)**: a generic Microsoft Graph credential that you can reuse across other Microsoft nodes. When you select this option, make sure you grant the credential the scopes this node needs (for example, `Mail.ReadWrite`).
* **Microsoft Entra Service Principal (App-Only)**: app-only access through a Microsoft Entra app registration, with no signed-in user. Refer to [Microsoft Entra Service Principal credentials](/integrations/builtin/credentials/microsoftentraserviceprincipal.md) for setup and required application permissions.

Refer to the [Microsoft credentials documentation](/integrations/builtin/credentials/microsoft.md) for authentication information for this node.
