Update timeline

  1. identified Dec 06, 2023, 02:13 PM UTC

    Emails with a file attachment may not complete the file scan resulting in a quarantine result. The team is investigating the issue.

  2. identified Dec 06, 2023, 02:32 PM UTC

    The false positive rate includes emails without attachments as well. The team is continuing to work on the issue. Users will need to release false positive messages from the quarantine.

  3. resolved Dec 06, 2023, 03:52 PM UTC

    The scanning is operating as expected. By design and for security best practices, an incomplete scan of a message "fails to closed" and quarantines. Users must release messages from the quarantine if an email was impacted by an incomplete scan.
