I use my bb for work and work with the AS400 ISeries. On the Iseries, we use software to convert reports to PDF files and email them to our Lotus Notes server. Sometime over the past weekend, the pdf files have begun failing to retrieve by the bb device. No bb error. I get the little transfer arrows and a little thinking hourglass but then nothing opens. Regular pdf files sent outside the Iseries are fine. Iseries .txt files are fine. The Iseries pdf files open fine on the Lotus Notes desktop.
The Iseries software did not change because that's my job. Networking tells me that nothing changed on the BES either. When I take an old pdf file from my desktop, something from before this problem occurred, and send it to myself again, it now fails to open.
Has anyone experienced this or something similar?
