I have the same PDF corruption problem in two different offices that I am the tech support for.
Office 1:
Started in the middle of December. PDF received from outside the office and is viewable with no problems. I have no control over how it is created. If it is forwarded to anyone else, the PDF is corrupted. I have forwarded it to multiple people in the office. I have tried viewing with Reader 8, 9, Sumatra and Fox IT. I have tried forwarding to Gmail and their viewer says it is corrupted. If I save the PDF and create a new email, it will be corrupted when sent using Outlook 2003, Outlook 2007, Microsoft Live Mail and Outlook Express. If I create the email using Thunderbird 3, Gmail or the webclient Iclient for IPSwitch IMail it will not be corrupted. I have confirmed the same results when using our IMail SMTP and also Using Gmail as the SMTP server.
To be clear, if I created in Thunderbird, Gmail or Iclient and received on any of the MS products, it will be viewable.
This office receives PDFs daily from multiple sources. There is only a small subset that are having this problem. So far they problem PDFs are from two different companies they deal with, but not all of the PDFs are bad.
Office 2:
PDFs are created by a management system. I'm not sure what engine is used to create them. Same exact same issues.
At both offices, I noticed that the file size is wrong. One small PDF the proper file size is 12kb for the PDF when it's viewable, when it shows up corrupted it is only 8kb.
We handle the email for both offices. Both are POP servers, not Exchange. IMail was updated after these issues start. I have tried different SMTP servers and it still seems to happen only when using Microsoft products to send.
Anyone else having problems with PDFs getting corrupted? Any ideas how to find out a resolution?
