You can use Windows Messenger in conjunction with Hotmail to send and retrieve regular e-mail messages. By using your Hotmail mailbox, you can retrieve your e-mail messages from any computer that has Internet access.
To use Windows Messenger to send or retrieve e-mail through the Microsoft Hotmail service, click the More hyperlink in I Want To section of the Messenger window and then click Go to My E-mail Inbox on the pop-up menu. Doing this connects you to the Internet and opens the Inbox page for your Hotmail account on the MSN Hotmail Web site. You can then read your e-mail messages, reply to messages, and even compose new e-mail, using the buttons at the top of the page.
When you're logged onto Windows Messenger on your computer, Windows Messenger lets you know when new e-mail messages arrive in your Hotmail inbox by beeping at you and displaying a ScreenTip message (saying that you have new e-mail) above the Messenger icon on the Windows status bar.
