Why do I have failed files in the scan details of the Office 365 Securlet?


Office 365 Securlet


The failed column represents:

  • Documents that were deleted or locked whe the scan took place.  (We will retry failed files).
  • Files that are > than 30 MB are not sent to DLP.
  • Files marked to be retried because of throttling,429 error.

The failed files column will fluctuate with a sudden increase of new files to be scanned or as files are deleted or modified.

  • Failed files are retried daily for 30 days.
  • Files greater than 30 days will not be re-scanned. 

If you find a large number of failed files reported that have not cleared up over time, create a support ticket asking for details regarding these files such as:

  • the number of non-recoverable files
  • asking for a re-scan of failed files >30 days.

A re-scan may not touch these files as only exposed files will be re-scanned and only for 30 days for email.
