I've got a new Exchange 2003 server working and I now need to transfer the large Contacts list from my old Exchange5.5 server (which is on a different domain) onto the new 2003 server. Is there a folder or one file that I simply copy over? If so where would I find such a file or folder? I also need to copy one users mailbox over because of the years of emails that he wants saved. Is that an easy transfer? Is it simply copying the pst file and pasting it onto the new server? Any advise is appreciated. Thanks.
