What are you trying to name the test mailbox?
Do you have permissions to create the mailbox?
Are you able to modify the mailboxes you have migrated?

Hello,

since now I have not migrated any mailbox.
First I want to create a new one and test.
The name of the mailbox was GW001 or TESTGW.....

I have done all with the domain admin.

What exactly can I test ?

I have worked trough this manual:

http://www.msexchange.org/articles-tutorials/exchange-server-2013/migration-deployment/planning-and-migrating-small-organization-exchange-2007-2013-part13.html

After creating the DBs I will create the mailbox, since now without any success.
Please help me out or give me some other tests which I can do.

have you tried creating a mailbox via the shell?
see if you can create a new admin account using the following command, i usually create a user called exchadmin....

Get-Mailbox -ResultSize Unlimited | Add-MailboxPermission -AccessRights FullAccess -User ExchAdmin

Question:
I had some issues with AD Site. One subnet was wrong.
Now I want to prepare the Schema again but I have errors.
    Setup needs to contact the Active Directory schema master, but this compute
r isn't in the same Active Directory site as the schema master (1100-MyStreet).

Does the EXCH must be in the same SITE ?

is ad running on the exchange server? what you can do is  transfer over the schema master role  to the exchange box if its running ad..then run the setup again. once done you can transfer the schema role back to the original server. i have done this once and it worked when i got that error.
