I recently opened a case about this issue. Case # 16430105. Our users had previously been able to forward emails from hotels to the receipts@concur email address with pdfs of folios attached, and the images that would upload would be of the folio. Within the last 3 weeks our users are forwarding these emails and now the body of the email appears with a red x for the attachment. Something has definitely changed and no adequate response has been provided yet.
Any ideas?
Thanks!
