BlackBerry Mail is an email account that you create on your BlackBerry handset and can only access through your phone. Unlike other email accounts, there is no interface to access BlackBerry Mail messages through your personal computer. The one workaround involves forwarding these messages through your BlackBerry Internet Service (BIS) account so that you can view your BlackBerry Mail messages through another email account’s interface.
Log in to your BIS website from your personal computer (This is usually your mobile service provider’s website). Click the link that takes you to the BIS settings.
Choose the BlackBerry email account in question. Click “Options.” Click “Forwarding emails.” Enter the information for the email account you wish to use to view your BlackBerry emails through. Click “Save” and exit.
