"To force all users to use the basic client, you can add the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWEB\OWA registry subkey on the Exchange server. Set the value of the ForceClientsDownLevel subkey (of type REG_DWORD) to 1 to enable this feature (a value of 0 disables the feature).
In a front-end/back-end configuration, set this key on the back-end server, which generates the HTML coding and passes it to the front-end server, which then sends the HTML coding to the client."
