It is possible to specify a preferred TS License Server with Group Policy for Windows Server 2003 with Service Pack 1. Here is the procedure for setting the preferred TS License Server for 2000/2003 without using group policy:
Outlook 2003 uses Internet Explorer to display HTML messages. This can cause problems when attempting to print these messages from within Outlook.
This applies to Exchange Server 2003. It is possible that the behaviors of recipient policies of Exchange 5.5 and Exchange 2000 are similar, if not exactly the same as described here.
On a new installation of Exchange there is a Default Recipient Policy created that contains the email addresses specified during setup through the Internet Mail Wizard. This policy has a priority of lowest and a filter of all mailboxes.
