Hi,
I have copied all of the new policy files to my admx policy store. When I open up a GPQ to edit it, I get the following error message. After opening up the GPO files I see that they are trying to use a namespace of xxxxx14. I still have all of my Office 2010 templates in the system. Can they not be used together?
 Can I fix it without having any issue? I will be grateful to you. Thanks in advance.
Administrative Templates:
Encountered an error while parsing
Namespace
'access14.Office.Microsoft.Policies.Windows'is already defined as the target namespace for another file in the store.
File:
\…..comsysvol….access15.admax,line4,column87
Open up a GPQ to edit and get the error message
You are right. You should be able to use both together. I have actually encountered this myself and I have corrected it by changing the version in the following code to 15:
< ?xml version="1.0" encoding="utf-16"?>
< policyDefinitions revision="1.0" schemaVersion="1.0">
 <policyNamespaces>
   <target prefix="access15" namespace="access15.Office.Microsoft.Policies.Windows" />
   <using prefix="windows" namespace="Microsoft.Policies.Windows" />
 </policyNamespaces>
 <supersededAdm fileName="access15" />
 <resources minRequiredRevision="1.0" />
After doing this, what you need to do is to place all ADM files (download from this link first: http://www.microsoft.com/en-us/download/details.aspx?id=35554) under the folder named, "en-us".
If you are running on Windows 2008, you can try rewriting all your policy file to ADMX format.
