I've this configurations:
Two AD Domains (2 DC : xxx.local & yyy.local)
Two Exchange Servers (one for AD domain) --> THE EMAIL DOMAIN IS EQUAL!!!
In the first AD Domain (in the first exchange) i've the majority of the mailbox !!!
In the second AD domain I've 3 mailbox.
The mailbox in the second AD domain doesn't reach the mailbox in the first AD domain!!
The domain is not trusted!!!
What can I do?
