Hello we just upgraded from exchange 2003 to 2010. 2010 seems to be pushing people to stop using public folders. Public folders had the nice feature that you could see the contacts of the public folder in your address book. I haven't found a way to add shared contacts to the Outlook address book. How do you do it? If I am unable to find the solution I will likely have to go through the hassle of migrating the public folders over. I was having a problem with that so I went the route of shared contacts.

You could create your contact records in the Active directory. After all it is a directory server.
