Here's my setup:
Multiple domain trees in a single forest (for the sake of explanation, lets call them domain1, domain2, and domain3). Single Exchange 2003 Server, which is a member of domain1. Clients use Outlook 2010.
Each domain tree represents a different small company. There are people in the organization which need to be able to receive AND send email using email addresses from multiple domains.
Research leads me to believe that this isn't possible using just email aliases, that sperate accounts are necessary.
As a test, I setup an account for myself under domain2, and gave myself a mailbox. The mailbox was created, and I modified access and send as permissions.
I can't attach the second account to my Outlook profile, it says "Name cannot be matched to a name in the address list."
This appears to be an Offline Address List problem. I have verified that the AD email address matches the accounts primary email address.
Our Offline Address List is configured to build based on the Default Global Address List. When I preview the Default Global Address List, the subject user shows up, but it does not show up in the Offline Address List. I have rebuilt the Offline Address List. I have turned off Cached Exchange mode.
I have even increased the logging level of GAL building to maximum, and no errors are reported.
I'm hoping this is just something stupid, that I'm missing.
