Infrormation Centric Tagging (ICT) Classification buttons are not present but the plugin is loaded.
This can occur in situations that you have very restrictive environments, disallowing the users to access some parts of the system (e.g.: local drives).
Also can occur in situations where you have the plugin running embedded – opening from a browser, Outlook or any other GUI application.
For the specific case of Outlook, when you have restrictions accessing local drives and are opening files directly from the email window, you can do a Group Policy to apply the following reg keys:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security]
"OutlookSecureTempFolder"="%appdata%"
[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\14.0\Outlook\Security]
"OutlookSecureTempFolder"="%appdata%"
[HKEY_CURRENT_USER\Software\Wow6432Node\Microsoft\Office\14.0\Outlook\Security]
"OutlookSecureTempFolder"="%appdata%"
[HKEY_CURRENT_USER\Software\Wow6432Node\Policies\Microsoft\Office\14.0\Outlook\Security]
"OutlookSecureTempFolder"="%appdata%"
These keys will change the Outlook temp folder to a location where the user have access to.
