Add or Edit an Exchange Enterprise Source


Coveo will deprecate Exchange Enterprise sources on February 17, 2022. Any existing sources will remain operational until then. However, Exchange Enterprise sources can’t be added in organizations created in August 2021 or later.

Your users' email messages are received in and sent from Microsoft Exchange mailboxes. When you have the required privileges, you can add an Exchange Enterprise source to a Coveo organization to make the content of Exchange Online or on-premises Exchange mailboxes searchable (messages, conversations, contacts, attachments, and archives). When you select the Determined by source permissions content security option, each user can see and search their content only through a Coveo-powered search interface.

Leading practice

The number of items that a source processes per hour (crawling speed) depends on various factors, such as network bandwidth and source configuration. See About Crawling Speed for information on what can impact crawling speed, as well as possible solutions.

Create a Crawling Account

To allow Coveo to retrieve your Exchange Enterprise content, you must create a Microsoft Exchange crawling account that can access the Exchange content you want to index. See Source Credentials Leading Practices.

Leading practice
  • While you can use an existing account that meets the requirements, we recommend you create an Exchange account dedicated to Coveo. However, if you select the Determined by source permissions option in the Content Security tab, you might not be able to see this source’s content in the Content Browser, as your dedicated crawling account may not have any content directly associated to it.

  • If you ever change the account password, ensure to immediately update the password in the source configuration to prevent source update issues.

  • If you have an Exchange Online instance and cloud-based users, the account you create to crawl your content must have at least the following directory roles:

    • Exchange administrator

    • User administrator

  • If you have an Exchange on-premises instance and federated users, the crawling account you create must have full read access to the Exchange content that you want to make searchable. See Setting up a Full Read Microsoft Exchange On-Premises Account for further information.

Add or Edit an Exchange Enterprise Source

Before you start:

Then, to add a source, in the Add a source of content panel, click the On-Premises tab, and then click Exchange Enterprise.

To edit a source, on the Sources (platform-eu | platform-au) page, click the desired source, and then click Edit in the Action bar.

"Configuration" Tab

In the Add/Edit a Exchange Enterprise Source panel, the Configuration tab is selected by default. It contains your source’s general and authentication information, as well as other parameters.

General Information

Source Name

Enter a name for your source.

Leading practice

A source name can’t be modified once it’s saved, therefore be sure to use a short and descriptive name, using letters, numbers, hyphens (-), and underscores (_). Avoid spaces and other special characters.

Instance URL

Enter the base URL of the Exchange instance that you want to make searchable. Ensure to include the protocol (https://).

  • To index all mailboxes:

  • To index the mailbox of a single user: link:[ExchangeOnlineUserEmailAddress]

  • To index all public folders:

Character Optical Recognition (OCR)

If you want Coveo to extract text from image files or PDF files containing images, check the appropriate box. OCR-extracted text is processed as item data, meaning that it’s fully searchable and will appear in the item Quick View. See Enable Optical Character Recognition for details on this feature.


Contact Coveo Sales to add this feature to your organization license.

"Authentication" Section

  1. Under Exchange parameters, enter the credentials of your Microsoft Exchange crawling account. See Source Credentials Leading Practices.

  2. Under Azure AD parameters, paste the values you copied while creating your Azure Active Directory application:

    1. Under Client ID, enter your Application (client) ID.

    2. Under Client key, enter your client secret.

    3. Under Graph API endpoint, enter followed by your Directory (tenant) ID.

    4. Under OAuth 2.0 token endpoint, enter your OAuth 2.0 Token Endpoint (V1).

"Content to Include" Section

Clear the Archive check box if you don’t want to index archive mailboxes.

"Content Security" Tab

Select who will be able to access the source items through a Coveo-powered search interface. For details on this parameter, see Content Security.

"Access" Tab

In the Access tab, set whether each group and API key can view or edit the source configuration (see Resource Access):

  1. If available, in the left pane, click Groups or API Keys to select the appropriate list.

  2. In the Access Level column for groups or API keys with access to source content, select View or Edit.


  1. Finish adding or editing your source:

    • When you want to save your source configuration changes without starting a build/rebuild, such as when you know you want to do other changes soon, click Add Source/Save.


      On the Sources (platform-eu | platform-au) page, you must click Launch build or Start required rebuild in the source Status column to add the source content or to make your changes effective, respectively.

    • When you’re done editing the source and want to make changes effective, click Add and Build Source/Save and Rebuild Source.

      Back on the Sources (platform-eu | platform-au) page, you can review the progress of your source addition or modification.

      Once the source is built or rebuilt, you can review its content in the Content Browser.

  2. Optionally, consider editing or adding mappings once your source is done building or rebuilding.
