IMAP error: "The requested mailbox is not available on this server" - Need assistance with configuration

I switched my DNS records yesterday to point from an old Exchange 2003 server to a new one and moved all the mailboxes to the new machine. If people outside of my office try to access mail.mydomain.com, it seems some of them haven't received the DNS update yet because they get the error:

Task 'Checking for new mail in subscribed folders on mail.mydomain.com.' reported error (0x800CCCD2) : 'Outlook is unable to download folder (null) from the IMAP e-mail server for account mail.mydomain.com. Error: The server responded: 'REFERRAL imap://exchangeuser;AUTH=*@server1.production.mydomain.com/*] The requested mailbox is not available on this server.'. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Server1 is my old server which doesn't store any mailboxes anymore. Server1 is my new server. I have Server1 and Server2 as bridgeheads in the SMTP connector. How can I configure the system so that if anyone access Server1 they will still be able to check their mailbox even though it physically exists on Server2 now?

Try having the users who receive the error go into command prompt and type  ipconfig /flushdns

Propagation usually takes 24-48 hours in some cases longer, but usually it's cache that's causing the problem.

It's a lot easier to wait it out or have them use the ipconfig/flush command than to have server 2 continue to answer requests / act as another entry point etc.

Well DNS did propagate complete a few hours ago and no one is having errors anymore. However, I would like to know the solution to my question since that is why I am keeping server 1 alive.

Although, and correct me if I am wrong, but since server1 and 2 are bridgeheads they will accept mail for each other? Meaning if server2 goes down or is rebooted and mail comes into the domain, server1 will accept it and hold it until 2 comes back up and the mailbox store is available? Server2 holds the primary MX record and 1 is the secondary.

It sounds like your setup will work. How to have people still be able to access the mail when that server is down isn't possible. They can't access the mail when the mailstore is down.

But the one server should queue mail for the other based on your settings.

Did you configure the SMTP connectors also?

Here's more instruction to make sure it's configured 100% for both servers: http://www.cryer.co.uk/brian/msexchange/exch_as_a_backup_email_server.htm
