How to make URLs clickable in Office Communicator

Edit: This is the lame. All it does is make links that you send clickable. All incoming URLs are still plain text.

Source.

1. Open registry editor and go to the following registry entry:
   HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Communicator
2. Add the following key to above mentioned entry
   EnableURL (Type:DWORD), value can be either 0 (URL will appear as plain text) or 1 (makes URL clickable)

Now close the registry editor and restart Microsoft Office Communicator 2007, URLs should now be clickable. Administrators can control values of this feature via group policy settings.
