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

Hello same issue here...

The senders have iOS 9.3.1 installed.

Will try to make them update to the latest 9.3.2 to see if it gets better...

We've found the answer here. It's an Adobe PDF issue with Signatures/size. Here is a link explaining the issue and what to do. We've found that removing all signatures from the forwarded email allow the PDF to go through without corrupting.

This isn't an Adobe PDF issue at all. I've removed the entire signature and still same issue.

Apple please fix.

Has anyone heard from Apple yet?

No issues with the Android or BB on our Exchange 2010. The iPhone 6 has been updated to 9.3.2 and thats when we noticed the problem started. I've read other users' starting to see this since iOS 7 and now that we're at 9, they're still not getting it right.

It's a hit & miss and affecting 2010 or 2016 word/excel, pdf's, ppt documents. Forwarding these same documents from Android/BB devices, we're not able to replicate the problem. So no matter what Apple engineer is saying - the issue is within iOS 7 thru 9.3.2.

Hello all,

I have the same problem in my company with a lot of users affected by this.

I found this little workaround, waiting for Apple to correct this.

When the PDF document is opened,

click on the suitcase icon
Select the pencil
Select the white color
Draw a little white point in a white part of the document (you can of course adapt the color depending on the document...)
Press “OK”

Then send the mail; the attachment should work now.

I am able to get the PDFs to open in the Edge Web Browser and the Windows 10 Reader but not in IE via Adobe Reader DC.

We have the same error on some devices...

Like adell92 wrote: this works also on your devices.

Some of our users have 2 devices (iPhone & iPad).

This problem occurs (until now) only on one of this devices.

Means: The PDF - File forwarded from iPhone is working, from iPad is damaged...

Installed on iPhone / iPad is 9.3.2.

Beta not tested.

We are having this same problem. We run exchange 2010 and ios 9.3.2. Could it be an issue with poor signal strength. It seems like not all pdf's have this issue.
