We are running an Exchange 2003 server with a complete windows enviorment. We have two different domain names for two companies we run. We want to be able to get and send email from both email@example.com and firstname.lastname@example.org from the same Outlook session. I created the accounts and configured it, but every time we try to response to an email from company2 from outlook we get an error that we are don't have permissions to this reciepent. They can send and recieve from a Online Outlook access but would like to send and recieve from the local outlook program.
