Hello, We are using Exchange 2007 and have a domain trust to another companies forest. I have exported a user to PST and imported into our Exchange and now I want to give them access. I have read I can give them direct access as we have a trust in-place, but when I go to select that username I can't see anyway to select them to add? Hope you can advise Thanks

You will need to grant the permissions through ADUC, not through EMC, because the user isn't mail enabled. They will need Send As and either Receive As or Full Mailbox. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
