The SpamControl service provides email client add-ons to report Spam which was not correctly blocked to our central systems.
Since version 2010, Office is also available in a 64 bit version. If you have a 64-bit Windows installed, you probably also have the 64 bit Office installed. In order for the add-on to work, you should install the correct version that matches your Outlook version.
For Outlook 2007 you have to use the 32 bit version.
These are also compatible with the new Outlook 2013, both 32 bit & 64 bit.
