I looked at the RIM doc
BlackBerry Search Results and decided to disable PDFs until I can bring BES down for an upgrade.
I followed the steps exactly - and triple checked very carefully. I have restarted the attachment service, restarted BES... and it still served PDF attachments to handhelds. You can retrieve the entire documents.
Anyone had this issue? Or have any ideas how to troubleshoot?
