I am running a Windows 2008 R2 standard server with Remote Desktop Services Role.

My end users are login in using Remote Desktop Connection. When they open outlook 2010 on the server and they try opening a word or excell attachment, they get an error.

Word error: Word experienced an error trying to open the file. Try these suggestions....
 
Excell error: The file is corrupt and it cannot be open.

I save the attachment to a folder and when I look at the file properties I see the following text:

Security: This file came from another computer and might be blocked to help protect this computer
And there is a button: Unblock.

I wan't to disable this security setting so that the users can normal open and read their documents.

I found several solutions on Expert Exchange but none have work. I try the solution listed on the link below but I am not able to find the correct path.

http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/Q_27190501.html

I get as far as "User Configuration \ Policies \ Administrative Templates: Policy Definitions"

When I look under the administrative templates I do not find. these paths.

User Configuration \ Policies \ Administrative Templates: Policy Definitions: Beleidsdefinities\Microsoft Word 2010\Word Options\Security\Trust Center\Protected View\Turn off protected view for attachments opened from Outlook --> Enabled

User Configuration \ Policies \ Administrative Templates: Policy Definitions\Microsoft Excel 2010\Excel Options\Security\Trust Center\Protected View\Turn off protected view for attachments opened from Outlook --> Enabled

!!!! Please help !!!!

Navigate to User Configuration > Administrative Templates > Windows Components > Attachment Manager. Here you will find a couple of policies related to this feature, but to disable it you'll want to ENABLE the policy called "Do not preserve zone information in file attachments".

I already try that and then gpupdate. I also log off and log back in. I have not rebooted the server.

Run a RSOP on a client and see if it is picking up the GP correctly.

Just before I read your post, I found the solution on. Which indicates to change the settings of trust center under word and excel. I tested and it works, now i am looking into how to applied those setting under group policy. If not I will have to login to the server using RDC as every employee and make the changes. Do you know where in GPedit.msc those setting are located.

It looks like I am not able to find the settings under GPedit because I am running Server 2008 R2 STD 64bit. I just read that is not available in the 64bit, what up with that Microsoft?  So now I am looking into editing the registry.
