So I have been fortunate in my career to not have to deal with companies being bought/sold merging, etc that required 2 completely separate Exchange Environment's to be able to exchange email and free busy info.
So I have a couple of questions for those of you that have done this in the past. 1. what is the best approach to take so that we can look them up in our Exchange Environment and they can look us up in theirs? 2. I have read up on Federation but I still a little fuzzy on how the whole thing works. I am assuming since it says we can look up their free/busy info (and them ours) that it must give us some way of looking them up in the Gal right?
