i am in need of help here. I have a scenario of 2 Active directory forest.
Both are residing at different country. Now, ABC.com is hosting an exchange server where user from 123.com connects their mailbox all the way to ABC.com
I am going to setup an exchange at 123.com and migrate all the users over from abc to 123.
My plan is to have all users save their email into .PST first.
THen i will create mailbox for them, BUT i want to do it seamless where user feels nothing on the migration (the next day they come into office, they wont be having 2 account / password, when they run outlook, it connects).
My concern here is: when they run outlook, it connects automatically and they can send or receive email using the same email address they used to be.
Can i assume auto discover is the solution for me? if so, what should i set the auto discover URL?
assuming the autodiscover for abc.com is abc.com/autodiscover then what should be the autodiscover for the new exchange server in order to make it seamless and transparent for user?
