Exchange Category Manager is a plug-in for Exchange server 2010.  Without any interaction to the user's pc or Outlook® it enables you to manage the Outlook® categories and colors that are available to the users in Outlook® 2007 and higher.
You can define an unlimited number of groups with different users. Each group can have it's own set of categories and colors that the user can choose from.

Per user group you can either add colored categories to the existing list that a user has in Outlook or replace everything with the predefined list.

The plug-in is built with the Exchange Webservices API and can be installed on any 64 bit server that can connect to the Exchange server. It can safely run from the Exchange server itself too.

The installation does not add or replace dll's on the server and does not use the registry. Uninstalling is a matter of deleting the install directory and nothing will be left on the server.
