Exchange 2010 Global Address List Problem

I just migrated from Exchange 2003 to Exchange 2010 and I have some issues.  One main problem is the global address list.  Our oultook clients are all 2003 versions.  What seems to be happening is that the global list is not populating out correctly or Outlook 2003 is still trying to use the "remembered" addresses and not going by the new correct address.  Is there a easy way to force the outlook clients to refresh the contact list or just delete the remembered list out so they have to go into the global list and click on the name??  Any help on this and basic exchange 2010 knowledge would be greatly appreciated.  thanks.

Where are you seeing these addresses?

You are probably talking about the cached autocomplete entries in Outlook and not the Global Address List.

Is this when you start to type in the To box and it displays previous users? If so you need to delete the NK2 file from the profile.

Did you... "Rehome the Offline Address Book (OAB) generation server to [an] Exchange Server 2010"?
Migrating from Exchange 2003 to Exchange 2010

"Computers running Outlook 2003 and earlier or Microsoft Entourage require a public folder database (previously called the public folder store) to connect to Exchange"

"Exchange supports moving OABs only in the following configurations
Between servers running Microsoft Exchange Server 2010
From Exchange 2010 to Exchange Server 2007 servers
From Exchange 2007 to Exchange 2010 servers
From Exchange Server 2003 to Exchange 2010 servers"

"OAB version 4 (Unicode OAB)   This OAB was introduced in Exchange 2003 Service Pack 2 (SP2) and is supported by Outlook 2003 (SP2), Outlook 2007, and Outlook 2010. This Unicode OAB allows client computers to receive differential updates rather than full OAB downloads"

I have missed some steps in this migration somewhere.  It is working but isn't working correctly.  Both of you are on the right track on this.  I still show a offline address list from the old exchange server on the new exchange server and 1 box is doing some strange things.  The owa version on exchange has 2 different ones, light and premium i believe.  All email accounts will open up into the premium with no issues but 1 box.  No matter what i do it always opens up the the light version.  I even applied a rule that tells it to open in premium but it will not work.  
Making Bulk Changes to Active Directory

Watch this video to see how easy it is to make mass changes to Active Directory from an external text file without using complicated scripts.

Run the Best Practices Analyser from Exchange Management Console --> Toolbox and select Health Check from this tool.

Report or deal with any issues found there.

The offline address book can be regenerated if necessary. It is the global address list that you should concentrate on at the moment. There will be only one Global address list for the mailbox users.

If you use Outlook Web Access or you set up a new user and log into a PC with new user and configure Outlook 2003 does this all work ok?

Have you removed the NK2? What was the outcome?

Here is a screen shot of the error i received
hmmm, and what does it say when you click the link for more info?

This may not be related to the problem at hand. What results do you get when the NK2 is deleted? and can you run the fresh user test?
