Adobe Reader DC can't open files in Microsoft Personal Vault

[PaulaCR]

When trying to open a Microsoft Personal Vault PDF with Adobe Acrobat Reader DC (my default application for PDF files), I get error "There was an error opening this document. Access denied". I can oprn the file with Adobe Acrobat Reader DC when the file is not in the Personal Vault and I can open the file in teh Personal Vault with Adobe Reader Touch.  However, Adobe Reader Touch does not provide all teh features I want that are in Adobe Acrobat Reader DC.  What do I need to do to get Adobe Acrobat Reader DC to open files in the Microsoft Personal Vault?

Not sure but I would think the Vault is stopping Adobe Acrobat reader from accessing the files. You have to Allow access to your vault> I would think you do that on the One Drive, your account, settings.

I would post this question over on the MS forums as it's a problem with One Drive not Reader

I'm moving this question from Forum Community Help to Acrobat Reader.

Would love an answer/solution to this question as I'm having the same issue. Didn't know Adobe Reader Touch works with it though, so I'll try that for now.

I found two workarounds.  

• you can open the files with MS Edge.  You can print the documents from there.
• The way I liked better was just to copy or move the files into another folder outside the vault.  They will open then.  

A bit of an inconvenience but at least you can get to your files until MS does something to fix the problem

It doesn't sound like a Microsoft problem. If other apps can open the files then it sounds like it's a problem with Adobe Reader.

I agree.  Microsoft Personal Vault encrypts the files. I believe that the problem is that Adobe Reader cannot decrypt the files.
