    Exchange 5.5 migration to Exchange 5.5

    When we decided to move our Exchange 5.5 from one NT4 box to another at work, I read through lots of info from Microsoft, and after some irritating errors (and mistakes) I finally decided to take the "quick and dirty" way. Since there were only 11 mailboxes on the old server, I...
