# How to onboard Microsoft 365

{% hint style="info" %}
This feature is included with a Cortex XSIAM Premium license. It is also included with any other Cortex XSIAM license that has the Cloud Posture Security or Cloud Runtime Security add-on.
{% endhint %}

You can add Microsoft 365 as a third-party data source in Cortex Cloud Data Security.

* You have generated a Globally Unique Identifier (GUID), also known as a Universally Unique Identifier (UUID). You will need this ID for the tenant you want to use for the Microsoft 365 instance.

2. On the Data Sources & Integrations page, click + Add New.
3. On the Add Data Sources or Integrations page, search for Microsoft 365, then hover over it and click Add.
4. On the Microsoft 365 integration instance settings page, do the following:
   1. In the Display Name field, enter a name for your Microsoft 365 integration instance.
   2. In the Tenant ID field, enter a tenant ID.
   3. In the Region list, select a region.
5. Click Next.

#### **Authorization**

1. On the Microsoft 365 Instance screen, if you are an administrator, click the click to authorize link.
2. If you do not have administrator permissions, follow the instructions on screen and click Close.

The Microsoft 365 instance should now appear on the Data Sources screen under 3rd Party Data Sources.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsiam/configure-cortex-xsiam/cortex-xsiam-data-sources/vendor-specific-data-sources-and-connectors/microsoft/microsoft-365-posture/how-to-onboard-microsoft-365.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
