Old AD Forest: abc.com Win 2003 R2
Existing Exchange: Exch 2007 SP3
Exchange Server contains the domains like aaa.com, bbb.com, ccc.com so on and so forth
Created new AD Domain ccc.com
Deployed Exchange 2013 SP1
Trust created with conflict. the conflicting object is ccc.com in both ADs
I can send emails from new exchange organization to aaa.com, bbb.com, etc except to ccc.com user in abc.com
Kindly suggest how to enable mail flow
