Access is denied – Permissions error, scan does not have the correct credentials to access the file, or additional access controls exist on the file, or AD access may have been interrupted, (try to manually access the files using the DLP scan user to see why the download failed)
Failed to Read – failed to read errors are generally related to files being locked and not available to be copied/downloaded
Failed to Download – often related to permissions errors (try to manually access the files using the DLP scan user to see why the download failed)
No such mount exists – this is related to file reader restarts, when the file reader does not unmount the drive fully during the restart and then the scan cannot mount the drive to continue scanning. This is a bug I have seen in the forums.
Exception occurred during initialization. Ensure that Microsoft Outlook is configured properly (.pst files). – Outlook needs to be installed on the server doing the scan to be able to read .pst files
