It is a best practice to lock down Ribbon and Quick Access Toolbar UI Customizations for Outlook on your RDS Session Hosts (Server 2008 R2). This will keep things consistant and prevent mistakes and helpdesk tickets.
But what if users want Quick Print or some other feature you didn’t initially plan for. Here is how to create a custom UI, while keeping things locked down.

Part 1:
In your Office 2010 GPO check that the following are set:
User Configuration/Policies/Administrative Templates/Microsoft Office 2010/Global Options/Customize –> Allow roaming of all user customizations
Then Enable –> Turn off user customizations via UI
On that Setting tab, also check –> Disallow in Outlook

Part 2:
On a technician machine, that does not have the GPO restrictions, setup your Outlook Quick Access Toolbar customizations to the way you want it for all of your users. Then look in your %LOCALAPPDATA%\Microsoft\Office for *.officeUI files and copy them to your file server.

Note: Exporting the settings directly from Outlook makes a slightly different file. *.exportedUI. So just manually copy the files rather than export them from within Office.
From that file server you can now either script the files to copy when the user logs on, or manually install them for certain users who want Quick Print etc.

Part 3:
On a Remote Desktop Session Host, close Outlook and perform a gpupdate /force to immediately see the changes to any GPOs you editted.
Now the user can re-open Outlook and the customizations should be seen.

In the end you should see something like this:
