We just switched from using local Outlook 2003 to Exchange 2003. We have a very large address book of external email addresses and distrubution lists (we're a property management company and have to contact our tenants individually and/or the whole building) that was manually copied from machine to machine and difficult to maintain. But now we want to export this local address book of tenants from Outlook 2003 and import the data into our Exchange Global Address book so we can all access the data and keep it maintained. I've managed to create a .pst file from Outlook but cannot figure out how to import the file in Exchange. I'm VERY frustrated and have tried to use other people's answers, but no luck! PLEASE HELP!
