SUMMARY
This step-by-step article describes how to install Microsoft MSN Messenger Service version 3.5 for Exchange 2000 on a computer that is running Microsoft Windows XP.

The messenger client that is included with the RTM version of Windows XP is Windows Messenger version 4.0. That version of the messenger client can be used only to connect to a Microsoft Network (MSN) server; you cannot use it to connect to a server running Exchange 2000. When you try to install MSN Messenger Service 3.5 for Exchange 2000 on a computer that is running Windows XP, you receive the following error message:

Installation cannot be completed because there is a newer version of MSN Messenger Service already on your computer.
