I am running an in house Exchange Server. We are moving to Rackspace for hosted Exchange. I have 15 users, some are still running Outlook 2003 and 2007. We are changing our domain when we move to Rackspace, but we have to keep our old domain email active for another few months. In a perfect world, I would like to be able to keep the old domain active and coming in to our Outlook accounts, and also set up the Exchange account from Rackspace in Outlook. Is there any possible way to do this in 2003 and 2007? I only have 2 users using 2010, and it is not feasible at the moment to upgrade everyone to 2010. I read a KB article from Microsoft: http://support.microsoft.com/kb/291626
but it seems like this has to be from the same Exchange server: from this comment: Note These steps assume that both accounts are on the same Exchange server.
Does anyone know of any solutions that I can pursue to make this happen? We are also set up for POP3 accounts with Rackspace, and I'm wondering if that is a good option to do while we still have to access our old in house Exchange email?
Thanks in advance for your help!
