email - Disable hover popup outlook

When i hover over an email contact, it produces a popup. How can I stop outlook from doing this

I tried file, options, general, user interface options, dont show screentips; but it seems that is not the option that controls it.

Answer

Here is a REG file that covers Outlook 2013 and 2010:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\15.0\Common\ContactCard]
"TurnOffHoverFunctionality"=dword:1

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Common\ContactCard]
"TurnOffHoverFunctionality"=dword:1
