<<>Note that it's a little more than a "rename" operation; this update >actually replaces the built-in "Exchange Client" software in Windows 95 with a new component called "Windows Messaging", that lives in a different directory. To minimize confusion, first remove the original Exchange client as follows: go into Control Panel.Add/Remove Programs, select the "Windows Setup" tab, clear the check mark in front of "Microsoft Exchange", OK back out, and restart Windows. Then run the "exupdusa.exe" download. Will this preserve folders, personal address book, etc.?>> Yes; removing Exchange will delete the binaries in the "\Program Files\Microsoft Exchange" directory (or wherever it was that the old version lived), but won't touch your .PST and .PAB files. The new version installs into \Program Files\Windows Messaging. Steve Dirickson WestWin Consulting (360) 598-6111 [log in to unmask]
