    Caution:
    If you tap Close, you'll need to configure your passcode in the iPhone Settings application before you can view your information on your iPhone.

What else do I need to know?

• If you are prompted to create a passcode and don't create one, you won't be able to send and receive e-mail.
  
• The Apple iPhone running software version 3.0 requires you to use an alternate server name. To find that server name, sign in to your account at the following address: https://pod51000.outlook.com/owa/. After you sign in successfully, the address you entered will resolve to an address that contains the server name you need to use. For example, if the address resolves to https://pod51005.outlook.com/owa, enter pod51005.outlook.com for your server name.
