The Disable Certificate Verification tool, CERTCHK.EXE, is used to enable or disable certificate verification checking on Pocket PC 2002, Pocket PC 2003, and Smartphone devices for testing purposes. When verification has been disabled, the mobile device will still use SSL to communicate with Exchange; it just won't verify the root CA against the device's certificate trust list. Instead of providing you with any warnings about the certificate, the mobile device will simply use the certificate. This is particularly useful if you have not yet used the Add Root Certificate tool to add your organization's internal root certificate to a mobile device but you want to test SSL connectivity from the device to Exchange.

For more information on using CERTCHK.EXE, see the Read Me file included with it; however, do keep in mind that this tool is for testing purposes only and should not be used in production environments.
