SUMMARY

This article describes how to set Exchange 5.0 client as the default e-mail program.

MORE INFORMATION

By default, Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows 98 Second Edition, Microsoft Windows NT 4.0, Microsoft Windows Millennium Edition (Me), Microsoft Windows 2000 Professional, and Microsoft Internet Explorer only recognize Microsoft Outlook, Microsoft Outlook Express, and Microsoft Hotmail as valid e-mail programs. After you install the Exchange 5.0 client program, if you start Internet Explorer, click Internet Options on the Tools menu, click Options, and then click Programs, the Exchange 5.0 client program is not displayed. To set Exchange 5.0 client as the default mail program, add the following registry keys to the registry:

• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols\mailto
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols\mailto\DefaultIcon
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols\mailto\shell
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols\mailto\shell\open
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\Protocols\mailto\shell\open\command
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\shell
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\shell\open
• HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Exchange\shell\open\command
