I have 2 domains domain1.local and domain2.local
I need to be able to host both domains on one exchange server. I have created a root domain in a new forest called headoffice and have domain1 and domain2 as members of that forest. I have a dc for the headoffice domain, a dc for domain1, and a dc for domain2. My exchange server is installed on the headoffice domain.I have setup users in both domain1 and domain2 with e-mail accounts. I have created 2 new recipient policies reflecting domain1 and domain2. What do I have to do to be able to logon to domain1 as a user and be able to access my exchange account, at the moment if i create a user in the headoffice domain I can log onto a mailbox (this makes sense because the exchange server is installed in the root domain). If I log a user on to domain1 or domain2 and try to open their mailbox, I get a 'You do not have permission to logon'
All help appreciated
