We upgraded from 4.5 to 2014 in October and are now noticing that customers are occasionally getting the wrong PDF's emailed to them. We have Paperless Office set up to email our Sales Orders as a confirmation to customers so they can check the items and quantities before we ship. We have now heard from 2 different customers within a week that they are having seemingly random sales orders emailed to them instead of their own. One customer had an incorrect sales order emailed that was from an account without Paperless Office set up. This seems like there are some sort fields or something out of whack but I have not been able to find any clearing utilities for Paperless Office. We use a remote desktop connection and the emails are coming to the customer  from a no-reply email address. Does anyone have any suggestions?
