I have Windows Phone 10, Outlook, and all latest updates. I installed Microsoft's PDF reader app (I also tried the Adobe app).

I open an email and tap on a PDF attachment. Instead of opening, it tells me that I need an app and should search the store. I click "Yes", it takes me to the store, and a blank page is shown.

How do I open PDFs in Outlook?

PS: I also tried saving the file to the phone, and opening it in the File Explorer app. But it doesn't get saved, and the file is not there!

  • Is this happening with all attached pdfs or just one. I doubt if might be the pdf is corrupted. Jun 15, 2016 at 5:42
  • By default, edge opens the pdf documents and i just tried it now, please try with other attachments, as Swetha said, it might be a corrupted pdf!

  • All PDFs. Actually this problem has been reported before many times. Pity they haven't fixed it yet. Images open properly, just PDFs that don't.

  • @qphone Uninstall the Microsoft's PDF reader app. Then install an another reader like Foxit or Adobe. It worked for me that way. I think it is problem with the PDF reader app.

I have the same behaviour. But the JPG attachments are also unable to open. If I click to forward the email, I can open the attachments without any problem. It's simply a bug.


I re-installed the PDF reader app from Microsoft and now everything works fine.


PDF reader app is about EOL. Open PDF using Edge now on-wards.


First of all download the PDF Attachment from Outlook. Then click on it. A list of PDF readers option will be shown to you(I have Adobe Acrobat Reader and PDF Reader), click any one. The PDF will open.
