Testing DLP Network Protect file quarantine of SharePoint Discover scans and DLP is successfully quarantining the file and leaves marker file in the original file location, however, only the service account(the account configured in DLP to perform the scan and quarantine actions) is able to see marker file. The user that created/uploaded the files that were quarantined cannot see the marker files.
The files were located under “Files with no checked in version” on the SharePoint server.
