* Windows Messaging: This is a 3 MB update for Win95; it already
       comes with NT 4.0. It replaces all of Exchange's components
       including Internet Mail, and provides most of the bug fixes. You
       should still get the Cover Page update, and read Sue Mosher's
       FAQ if you use MS Fax and want to use this update.
     * Exchange Server Client: This is a massive 9 MB download that MS
       could've easily packaged up and sold, but instead decided to give
       it away. This is the same client that MS ships with Exchange
       Server. It installs into the exact same place as the built-in
       Exchange (which means far less confusion for Win95 users), and
       includes much of the functionality provided by Internet Idioms.
     * Microsoft Outlook: A replacement front end for Exchange. This
       ships with Microsoft Office 97. It combines Exchange and Schedule+
       into one interface, and includes a very nice add-in manager which
       lets you disable troublesome extensions, such as Internet Idioms
       (which doesn't work with Outlook, by the way). I haven't seen much
       of this, but it does appear to turn Exchange upside-down and
       inside-out. Anthony has most of the answers in the Outlook 97
       FAQ.
