    Error opening PDFs from Outlook in RDS 2016 environment

      Hi,

       

      I'm not sure if the fact that the scenario is running Outlook in a Windows Server 2016 Remote Desktop Environment with a User Profile Disk enabled for storing users profiles is relevant or not, but for transparency I'm starting with that information.

       

      It also seems to occur if you log on to a host locally and not through the RDS environment.

       

      Basically, the issue boils down to when Protected Mode is enabled, a PDF attachment in an email cannot be opened and fails with the error "There was an error opening this document. Access is denied."

       

      I traced the problem down to being a write access issue on the Outlook Secure Temp Folder location C:\Users\<user>\AppData\Local\Microsoft\Windows\INetCache\Content.Outlook\<random string>\. It seems when opening the file in Outlook, the PDF is created there but as Adobe Reader tries to access it a write request is denied and then Reader fails to open it with the above error.

       

      The version of Adobe Reader DC is 18.011.20040.19174
