Hello. I have a problem with configuration Exchange 2013 in my organization. We have one forest, and two domains - parent xxx.local, and child - yyy.xxx.local. They have a trust relationship between them as parent-child. Exchange server 2013 with mailbox and CAS role installed in domain xxx.local. Users in domain xxx.local don't have any problem but I have a problem with users in child domain. When I configure mailbox for user in child domain in Outlook 2010 the program ask credentials for logon to server and no credentials are working. In the same time OWA for this user is working excellent with credentials yyy\username.
Any ideas? Thanks.
