• From the Folder List, right-click the Inbox and select New Folder.
• In the Name field, type BlackBerry Internet Service.
• Make sure the Folder contains field is set toMail and Post Items, then clickOK.
• From the Folder List, right-click the BlackBerry Internet Service folder and selectProperties.
• Click the Home Page tab.
• In the Address field, type the address to your service provider’s BlackBerry Internet Service web site.  Note: To find your service provider’s BlackBerry Internet Service web site, visit the Support section at www.blackberry.com.
• Select the Show home page by default for this folder check box, then click OK.

To access the BlackBerry Internet Service in Outlook

• Open Outlook.
• From the Folder List, click the BlackBerry Internet Service folder. The BlackBerry Internet Service web site appears.
• Log in to your BlackBerry Internet Service account.

• Start Windows Live Mail via the Start button or other link. When Windows Live Mail opens, click Tools, then Accounts from the menu bar. (If the program’s menu bar is not visible, hold down the Alt key and press the letter T, then release both keys.)

The “Accounts” window appears:

• Highlight the e-mail account you wish to change and click Properties. The “Properties” window appears:

You should not need to change any of the settings on the General tab.

Set the advanced properties:

• Click the Advanced tab, then check the Leave a copy of messages on server checkbox.
• To make sure copies of every message don’t stay on the server forever (which can slow down your mail connections and use up your disk space allowance), we also recommend checking the box marked “Remove from server after XX days”. Choose a number of days that’s long enough that you’ll be able to read the messages in your other mail program (or Webmail).
• The “Remove from server when deleted from ‘Deleted Items’” checkbox controls whether an email that you delete from your computer will also get deleted from the server before the number of days specified above is reached. If you check the checkbox, then messages deleted from your computer will always be deleted from the server. If you do not check the checkbox, then messages deleted from your computer will not be deleted from the server until the specified number of days has passed (assuming that the “Remove from server after X days” checkbox is checked).

Close the setup windows:

• Click OK to close the “Properties” window, then click Close to close the “Accounts” window.

Windows Live Mail configuration is complete:

• You’re finished! From now on, any mail that arrives should stay on the server, and you should be able to see it in your other mail program or Webmail. (If you’re using another mail program, you’ll probably want to setup that program to leave a copy of your messages on the server, too.)
