Files that fail scanning, or that the scanner quarantines, cannot be previewed, downloaded or reviewed. This guide covers the four things you can do with them.

**Before you start:** you need document write access. Legal holds and disposal are owner or manager actions.

## Find the file

Open **Inbox › All invoices** and choose the **Blocked** filter, or follow the cross-link from the Review list. Each row shows why it was blocked and when.

## Request a rescan

Choose **Request rescan** when the block looks like a transient scanner problem. The file is queued again and returns to the normal flow if it passes.

## Release a false positive

Choose **Release** when you are confident the file is safe, for example a PDF from a known supplier that a signature rule flagged. Give a reason. The release is recorded with your name, and the file continues to review.

## Place or release a legal hold

Choose **Legal hold** when the file must be kept regardless of its state. Pick the reason: legal review, customer dispute, regulatory request or incident investigation. While a hold is active, disposal is disabled and the reason shows inline. Release the hold when the matter closes.

## Dispose of the file

Choose **Dispose** to remove a file that should never have been uploaded. Disposal is disabled while a legal hold is active. The record of the upload and the disposal remains in the audit trail; the file content is removed.
