Okay all you gurus, let me have it for being dumb, but help me out! I attempted an in-place upgrade to SBS 2000 on an SBS 4.5 server, which blew up in the middle (said it was out of disk space, but had over 4gb more than required). At any rate, my decision was to go on and do a fresh install of SBS 2000. I have the system running well now, but don't know how to get my Exchange 5.5 mail into the Exchange 2k system. What are my options? Do I have to install a 5.5 Exchange server and do a migration or is there a utility that will read the MBDATA files? Will it do replies correctly after importing messages into 2k system? x.400 addresses are different aren't they? I also am having trouble getting Internet mail to go OUT of the server. It is comig in just fine, but will not go out -- it just sits in the queue. Need input!!! Signed....., Tired from all the late nights getting nowhere.....
