Mail Unable To Show Groups

I have over 20 different Groups set up. In the good old Outlook Express Address Book, I could open a Contact and in the "Other" tab. I could see a list of all the Groups that the person belongs to. In Windows Mail Contacts. I successfully imported all my Contacts and Groups. But. is there a way to find out which Groups a person belongs to? It's too time consuming to manually search through each of my 20 groups. The Help section claims that Windows Mail has all the features of Outlook Express. but the list of Groups a person belongs to is obviously missing. It looks like Microsoft is selling us a degraded product ("Address Book Minus" instead of "Address Book Plus") and is calling that an improvement!!!!

Please prove me wrong. Show me that I can display a list of Groups for each person. I rely heavily on Groups. Just for example, if I have multiple entries for the same person (with different email addresses), I can tell which one is the most current by looking at which email address is part of a recently set up Group. If Microsoft Mail is unable to show me a list of Groups for any one individual Contact, is there a way I can continue using Outlook Express under Windows Vista Ultimate x64?
