I'm kidding banging my head with this one and need some insight. There is a two way trust between DomainA & DomainB
We have external users on DomainB that was primarily used for sharepoint authentication through the domain trusts.
Now there is a SMTP requirement to have users in DomainB be notified for custom sharepoint tasks.
I wanted to create Mail Users & add existing users within Exchange 2010 for those users but Exchange only sees the Organizational Unit for DomainA.
USERS (Need to Add Existing Users SMTP addresses).
Hope I didn't lose you and thank you for any insight.
