Outlook 2003, 2007 & 2 different Exchange Accounts

Posted on 2011-10-27

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:   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!

    Outlook 2003 and 2007 do not support multiple Exchange Accounts

    I beleive if sticking with 2003/2007 you could set them up with Exchange/POP3/IMAP accounts.

    However, you need to be aware if using Multiple Accounts in 2003/2007 the default mail account will always be the Exchange Account

    Which might not be practical, if your interested in retaining the previous domain name

    Might be more practical than you thought to upgrade the remaining users to 2010

    Thanks for your response Apache!
    We are only keeping the previous domain name for a few months, trying to get this to be even less.  Is there an issue with it being the default for a short time?  Is the issue just being that they have to click on the other account within Outlook to find the new domains email?

    Also, just a stab in this topic for you, and if I should post it elsewhere, I will.  Do you know where on the Exchange server I need to point to one particular exchange mailbox that I want to migrate to Rackspace?  This one is a Mac user and has been using MacMail, but ever since we changed our firewall NO ONE, can get his computer synced to the server anymore.  My Entourage people are fine!

    That previous question didn't quite make sense:

    I need to find how to migrate this one particular mailbox.  So I need to find where the mailboxes actually are on the Exchange server so I can tell Rackspace how to help me migrate it.  I don't know where the mailboxes actually are on the Exchange server???
