Currently the Adobe Acrobat add-on for Microsoft Outlook leverages the "received date" to timestamp the messages. It would be nice to have the option to use the "sent date" of the message instead for the timestamp. There are instances during email migrations where the top level received date header gets updated to the new mail system it got migrated to. When that happens, the received date changes on the message in Outlook. When organizations are providing PDFs for public records requests or legal requests, the queries in the ediscovery tools search by the "Sent" date of the message. Generally with emails traveling fairly instantaneously, the discrepancy in date/time is negligible. But in instances of these messages when they are migrated to a new email system, the discrepancy can by significant and the date used in the "convert to pdf" now becomes "inaccurate".
