Enterprise websites Graph connector

The Enterprise websites Graph connector allows your organization to index articles and content from its internal-facing websites. After you configure the connector and sync content from the website, end users can search for that content from any Microsoft Search client.


Read the Setup your Graph connector article to understand the general Graph connectors setup instructions.

This article is for anyone who configures, runs, and monitors an Enterprise websites connector. It supplements the general setup process, and shows instructions that apply only for the Enterprise websites connector. This article also includes information about Troubleshooting and Limitations.

Step 1: Add a Graph connector in the Microsoft 365 admin center

Follow the general setup instructions.

Step 2: Name the connection

Follow the general setup instructions.

Step 3: Configure the connection settings

To connect to your data source, you need to fill in the root URL of the website, select a crawl source, and the type of authentication you'd like to use: None, Basic Authentication, or OAuth 2.0 with Azure Active Directory (Azure AD). After you complete this information, select Test Connection to verify your settings.


Use the URL field to specify the root of the website that you'd like to crawl. The enterprise websites connector will use this URL as the starting point and follow all the links from this URL for its crawl.


If the site you want to crawl has a sitemap defined, the connector will only crawl the URLs listed in the sitemap. If no sitemap is defined, the connector will do a deep crawl of all the links found on the root URL of the site.

Crawl mode: Cloud or On-premises

The crawl mode determines the type of websites you want to index, either cloud or on-premises. For your cloud websites, select Cloud as the crawl mode.

Also, the connector now supports crawling of on-premises websites. To access your on-premises data, you must first install and configure the Graph connector agent. To learn more, see Graph connector agent.

For your on-premises websites, select Agent as the crawl mode and in the On-Prem Agent field, choose the Graph connector agent that you installed and configured earlier.

Basic Authentication requires a username and password. Create this bot account by using the Microsoft 365 admin center.

OAuth 2.0 with Azure AD requires a resource ID, Client ID, and Client Secret. OAuth 2.0 only works with Cloud mode.

For more information, see Authorize access to Azure Active Directory web applications using OAuth 2.0 code grant flow. Register with the following values:

Name: Microsoft Search
Redirect_URI: https://gcs.office.com/v1.0/admin/oauth/callback

To get the values for the resource, client_id, and client_secret, go to Use the authorization code to request an access token on the redirect URL webpage.

For even more information, see Quickstart: Register an application with the Microsoft identity platform.

Step 3a: Add URLs to exclude (Optional crawl restrictions)

There are two ways to prevent pages from being crawled: disallow them in your robots.txt file or add them to the Exclusion list.

Support for robots.txt

The connector checks to see if there is a robots.txt file for your root site and, if one exists, it will follow and respect the directions found within that file. If you do not want the connector to crawl certain pages or directories on your site, you can call out those pages or directories in the "Disallow" declarations in your robots.txt file.

Add URLs to exclude

You can optionally create an Exclusion list to exclude some URLs from getting crawled if that content is sensitive or not worth crawling. To create an exclusion list, browse through the root URL. You can add the excluded URLs to the list during the configuration process.

Step 4: Assign property labels

You can assign a source property to each label by choosing from a menu of options. While this step is not mandatory, having some property labels will improve the search relevance and ensure more accurate search results for end users.

Step 5: Manage schema

On the Manage Schema screen, you can change the schema attributes (the options are Query, Search, Retrieve, and Refine) associated with the properties, add optional aliases, and choose the Content property.

Step 6: Manage search permissions

The Enterprise websites connector only supports search permissions visible to Everyone. Indexed data appears in the search results and is visible to all users in the organization.

Step 7: Set the refresh schedule

The Enterprise websites connector only supports a full refresh. This means that the connector will recrawl all the website's content during every refresh. To make sure the connector gets enough time to crawl the content, we recommend that you set a large refresh schedule interval. We recommend a scheduled refresh between one and two weeks.

Step 8: Review connection

Follow the general setup instructions.


When reading the website's content, the crawl may encounter some source errors, which are represented by the detailed error codes below. To get more information on the types of errors, go to the error details page after selecting the connection. Select the error code to see more detailed errors. Also refer to Manage your connector to learn more.

Detailed Error code Error message
6001 The site that is being tried to index is not reachable
6005 The source page that is being tried to index has been blocked by as per robots.txt configuration.
6008 Unable to resolve the DNS
6009 For all client-side errors (Except HTTP 404, 408), refer to HTTP 4xx error codes for details.
6013 The source page that is being tried to index could not be found. (HTTP 404 error)
6018 The source page is not responding, and the request has timed out. (HTTP 408 error)
6021 The source page that is being tried to index has no textual content on the page.
6023 The source page that is being tried to index is unsupported (not an HTML page)
6024 The source page that is being tried to index has unsupported content.
  • Errors 6001-6013 occur when the data source is not reachable due to a network issue or when the data source itself is deleted, moved, or renamed. Check if the data source details provided are still valid.
  • Errors 6021-6024 occur when the data source contains non-textual content on the page or when the page is not an HTML. Check the data source and add this page in exclusion list or ignore the error.


The Enterprise websites connector doesn't support searching data on dynamic webpages. Examples of those webpages live in content management systems like Confluence and Unily or databases that store website content.
