Emails with attachments falsely flagged as malware

I’m having an ongoing issue with some emails containing attachments saved in our project folders on Box being falsely flagged as malicious.  I can’t mark them as safe myself, as I don’t have the admin rights. I am co-owner of the folder though, so I get all the notifications, but as the pop-up notification doesn’t include the full file name, its not possible for me to search for the file to log a request to mark it as safe.
ICT understandably can’t lower the security settings across our entire enterprise account. is there anything else that can be done to enable emails from trusted senders to not be falsely flagged - the would have already been scanned for malware when they came through our email client.
