The GroupWise 7 client is supported on Microsoft Windows 2000, Windows XP, and Windows 2003. GroupWise also has a special WebAccess client that can be used through any of the popular Internet-browsing programs, such as Microsoft Internet Explorer and Mozilla Firefox. Using the WebAccess client, you access your GroupWise account from other operating systems that support web browsing, such as Macintosh, UNIX, and Linux. You can also use a personal digital assistant (PDA) or a wireless telephone to access information in a GroupWise system. No matter which one you use to access GroupWise, each client or device has basically the same features, but the way you use those features can vary depending on the capabilities of the environment.
In this book, we emphasize the GroupWise client for the Microsoft Windows platform. We also devote several pages to the GroupWise WebAccess client. These are the two most commonly used means of accessing your GroupWise account. Appendix A, "GroupWise Cross-Platform Client," discusses the GroupWise Cross-Platform client that you can run on a Macintosh or Linux workstation.
No matter which method you use to interact with GroupWise, all GroupWise users deal with common message formats. It doesn't matter which version of the client you use to create a message, and it doesn't matter which version of the client the recipient uses to read the message. (In fact, if you are communicating through the Internet with users outside your company's GroupWise installation, those users are very likely using completely different email systems.) The point is that you can send messages to people using different email systems, different computing platforms, and different email interfaces without knowing anything about those other systems, platforms, or interfaces.
