Hi,
First let me explain my Exch 2013 SP1 Multidomain set up.
1. DA as Forest Root domain, having schema master domain role installed.
DB as Tree Root domain in above forest
DC as Child domain in Tree root domain.
2. After set up, I have ran 'netdom query fsmo' on each DC. It displayed schema master role on forest DC and domain role on individual DC on which command was run.
3. Now to install Exch 2013 SP1, ran appropriate command on forest DC (i.e PrepareAD, Prepareschema and alldomain).
4. Brought 1 machine in Child domain and installed Exch 2013 SP1 server on it.
Now, when I access ECP, Create user, new mailboxdatabse etc. options available only if login to ECP by ForestRootDomain\administrator credentials. please confirm.
while creating new user, it shows User Login Name with Child.TreeRootDomain.local default but after creating user, it shows Username@ForestRootDomain.local as Email address. Please confirm.
Thanks and regards,
Sudhir
