iOS 7.1 Exchange PDF viewing

We have a fleet of iPads and iPhones that are having issues with iOS 7.1 and PDF attachments.


If we send the PDF that is having issues to an email on our exchange server then the PDF file will open as a blank white or black screen. If then sent to any other app it will not open (We use PDF Expert)


If we change any of the following it works and open just fine.


  • Use a gmail address and the same mail app.
  • Use the same PDF but opened and saved in a different PDf compatibility setting.
  • Open the same PDF from webmail.
  • Use a device running iOS 7.0 and open the PDF


I've reproduced the issue with 3 iOS 7.1 devices.

iPad 2, iOS 7.1

We're also a IBM shop experiencing similar issues.

We run Lotus Notes/Domino and we are seeing the same issue so I don't believe this is an Exchange problem. It's an iOS one (IMHO)


I agree that this is an iOS issue, but am curious if you're running Lotus Traveler as your mobile platform? On our iDevices it's shown as an Exchange interface, as opposed to POP3 or GMAIL, etc.


Based on what I've read on this forum, the issue(s) doesn't exist with the other mail interfaces.

Yes, we are using Lotus Traveler as our mobile platform so the iDevices see it as an ActiveSync server as you say.


I thought we were just seeing this in pptx files but I had it happen in some PDF files and an Excel file yesterday.


Because we use Mimecast to archive our email our users can get the original attachment back from the archive, so I have a work around, but I would say that this is a very serious bug and a major issue for Apple and their relationship with business users. I'm very surprised it hasn't yet been resolved (or perhaps I shouldn't be ?)

The issue has not been resolved in 7.1.2 for us. Still having the same symptoms everyone is describing although it does seem to matter how the PDF was created. We are also having issues with PowerPoint Presentations. PPTX files are corrupted when you try to open them without first downloading the full message. Anyone else still having this issue after upgrading to 7.1.2?

Jul 3, 2014 11:11 AM in response to Jeff.Jacob

In case anyone is wondering why this happens: when the iOS device that's experiencing this issue downloads the message from Exchange and stores it in the local store, it converts the windows style \r\n newlines in the original attachment into *nix style \n newlines, corrupting the attachment. (I've seen this occur regardless of extension).

Tapping the "download full message" button preserves the original newlines from the message stored in Exchange.

The weird thing is that this doesn't occur on all of our iOS devices that are connected to exchange, but just some of them, and resetting the Exchange profile on the phone usually relieves the issue at least for a while. "Something bad happens" and then all future messages come through corrupted.

We have over 2000 mobile devices deployed and are experiencing this issue on iOS devices running iOS 7.X up to, and including 7.1.2.


Exchange 2007 server.

iOS 7.0.X and iOS 7.1.0 thru 7.1.2 are affected.


Workaround is to tap the "Download Full Attachment" link every single time. Pretty poor effort on Apple's behalf - this bug has been ongoing for a long time. We've been hoping for a fix every time an update is released - but no joy. Poor form.

Has anyone experienced issues on a newer version of Exchange higher than 2007?


I'm curious to know if it only impacts Activesync 12 and below, and if the problem occurs on Activesync 14 or above (Exchange 2010 and newer).


If you are experiencing this issue, could you state what version of activesync/exchange you're running?


Regardless - such a shame Apple is ignoring this issue.
