Report all attachments scanned by Advanced Threat Protection Safe Attachments
Currently reporting for Safe Attachments only shows malicious files. This makes it difficult to verify that Safe Attachment scanning is working as intended. It would be beneficial to be able to verify in a report detail regarding all attachments that have been scanned and marked as safe.
This idea stems from a situation were Advanced Threat Protection was not scanning attachments for a tenant despite being configured to do so. Without checking through message traces or verifying with end users it was not possible to verify if it was working or not. The issue was further complicated as the reporting for Advanced Threat Protection Safe Attachment File Types was showing nothing being found. It transpired that this only shows files if they are malicious so it was not a good indicator if the service was working.
