Briefly, what's happening is that the e-mail address is the same, but the e-mail is being delivered to a different place. So you just have to change your e-mail program's settings so you start reading from the new mailbox.
This isn't difficult, but you must do it at the right time. If you do it too soon, before we move the Web site, you'll miss out on e-mail that's arriving in the old mailbox. So we recommend you wait until you're sure the new Web site is live, and then change the settings. Keep a note of the old settings so you can change back if necessary, just in case you want to check the old mailbox for any lingering e-mail that still got delivered there.
We'll describe the process for Microsoft Outlook; it will be similar for other e-mail programs.
What you need to know
Before starting, you need to know:
- The e-mail user name: This is usually the bit in front of the "@" in your e-mail address. For instance, if your e-mail address is joe.bloggs@example.com, the username is joe.bloggs.
- The password
- The incoming mail server: This is "mail." followed by the domain name - e.g. mail.example.com.
Test the settings in Webmail
This is an optional, but recommended, step. It ensures the new mailbox is active, and that you've got the right user name and password.
First, send a test message to your e-mail address, do a "Send and Receive" in Outlook, and ensure that it does not arrive in your normal inbox (If it does arrive, that means the new mailbox isn't live yet, so you'll have to wait until it is).
We'll now check the new mailbox using your Web browser rather than your e-mail program. The Webmail address is "webmail." followed by your domain name - e.g. webmail.example.com. Go to this page in your Web browser and log in using the user name and password from above (click picture for larger version):

If you can't log in, it means either the user name or password is wrong, so try again, and if it still doesn't work, get the correct details from somebody who knows them.
If it does work, you should see the test message sitting there in the mailbox (click picture for larger version):

Delete it and log out of Webmail. Now you're ready to change the settings in Outlook.
Changing the settings
In Outlook, to see your e-mail accounts, go to the Tools menu and choose "E-Mail Accounts". Then click "View or change existing accounts". This shows you all your existing accounts (there might be only one). Select the relevant account on the left-hand side and click the "Change..." button. This displays a properties window for that account.
On this page, you're going to change three things: User Name, Password and Incoming Mail Server (click picture for larger version):

Make a note of the current settings first (and if you don't know the password, ask somebody who does know).
You only need to change three things: User Name, Password and Incoming Mail Server. Set these to the settings above for the new mailbox, and save the settings.
Testing
To test this, send a test message to the new e-mail address, do a "Send and Receive" in Outlook, and make sure that you receive it. That completes the testing.
