APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.
Run an estimate of the number of emails and documents in the source collection. To learn more about source collections (also known as searches in eDiscovery), see Collect data for a case in Advanced eDiscovery.
Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

HTTP request
POST /compliance/ediscovery/cases/{caseId}/sourceCollections/{sourceCollectionId}/estimateStatistics
If the estimate is started successfully, this action returns a 202 Accepted response code. The response will also contain a Location header, which contains the location of the estimateStatisticsOperation that was created to handle the estimate. Check the status of the estimate operation by making a GET request to the location, when successfully completed, the status will change to succeeded.
POST https://graph.microsoft.com/beta/compliance/ediscovery/cases/{caseId}/sourceCollections/{sourceCollectionId}/estimateStatistics
