PDF Attachments From iPhone Become Corrupt iOS 9.3
We are having an issue with PDF files becoming corrupt when sent from iPhone users in our Exchange 2013 environment.
The issue is happening intermittently, and every time it happens it is determined that the corrupt PDF attachment was forwarded from an iPhone (seems to be related to iOS 9.3.x)
When a PC user attempts to open the PDF, the receive an error message "Acrobat could not open 'PDFname' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded.)"
The file is only readable from an iPhone, or from the Mac OSX native viewer (will not open from Adobe on Mac either).
Interestingly enough, the corrupt PDF files CAN be repaired by opening the said PDF on a Mac using the native "preview" app, and using "save As" from there. The resulting PDF can then be opened from PC, Mac, Adobe, etc...
I would really like to make sure Apple is aware of this issue and is working to patch. It appears to be an iOS issue, and not an Exchange issue.
iPhone 6, iOS 9.3.1
