We are in the process of migrating from Exchange 2003 to Exchange 2010. As such, we have many Outlook 2003 SP3 clients in the field. One of the issues that has come up is with the ability to search Contacts in outlook 2003. While searching for emails in the inbox seems to work fine, searching contacts fails to return any results. This occurs with multiple user mailboxes - all migrated from our Exchange 2003 server. The contacts are there and accessible, but the search function seems broken. When we access these same clients from an Outlook 2010 client the search works just fine. Is this a known issue? Is there any possible work around?
