Outlook task categories removed after assigned tasks are accepted

I have recently upgraded to Exchange 2007 and seemingly after doing so, I can
no longer use my categories in my "Tasks". I create a task and assign it to
any number of pre-defined categories so I can easily sort by category which
worked nicely for many years. Now, when I assign the task to a user, and the
user accepts the task, the category is removed. That never happened before.
This is happening on both Outlook 2003 and Outlook 2007.
