Q. I'm using a Pocket PC 2003 to ActiveSync with Microsoft Exchange Server, but I receive certificate errors. What's the problem and how do I fix it?

A. Some Pocket PC 2003's have synchronization problems when you use certificates with ActiveSync. Fortunately, Microsoft provides a utility at http://download.microsoft.com/download/b/7/2/b72862f9-946e-489b-b8ea-1234a6eb597c/DisableCertChk.EXE that turns off the certificate checking that Pocket PC devices normally perform. The utility allows the ActiveSync to function fully. After you install the program on the PC, open a command prompt in the folder containing the tool and run

CERTCHK off

to turn off the certificate checking. You can read more information about the tool at http://www.microsoft.com/downloads/details.aspx?familyid=d88753b8-8b3a-4f1d-8e94-530a67614df1&displaylang=en.
