October 4, 2018 3:00pm – We just got word that a bad signature update for our email virus scanner was causing all Excel spreadsheets being sent as attachments to be blocked as viruses. This update was sent out today and we are not sure of the exact time the issues started but it seems to have been around noon. We have applied a fix to the signature and Excel files should go through fine now. We apologize for the inconvenience.
