I have recently installed exchange 2007 and it is coexisting with exchange 2003.
I have moved all mailboxes and replicated public folders to exchange 2007.
I have also removed the routing connection between the two exchange servers, changed RUS from exchange 2003 to exchange 2007 and mail is only going in and out of the exchange 2007 fine. Basically i think i am ready to uninstall exchange 2003 from the environment.
But one issue that i have found though is when I create a new mailbox on exchange 2007 the users name for that mailbox are displayed in the Address Book in OWA 2007 but not displayed in the Address Book in Outlook 2003 or 2007. Also I cannot configure the new users mailbox in outlook 2003 because it cannot find the users name during the setup process.
I have found the only way i can get the users details to appear in the Outlook 2003 or 2007 Address Book and configure the mailbox in Outlook is to move the mailbox to the exchange 2003 server and then back to exchange 2007 server. When this has been done the users name appears.
I have looked in the Management Console in Exchange 2007 and have noticed the Default Offline Address List is still using the exchange 2003 server as the generation server.
Could my issues have something to do do with the Default Offline Address List? If yes, would moving the Default Offline Address List to the exchange 2007 server fix the problem and can this be done whilst exchange 2003 exists?
