Disabling Certificate Security in Windows Mobile 5 to work with Activsync

Posted on 2006-04-20
Last Modified: 2008-01-09
I have an SBS2003 server with Exchange 2003SP2 installed.
Followed all of the instructions for configuring Windows Mobile 5 on the SBSERVER,

I have a Dell Axim X51V with Windows Mobile 5 Pocket PC Premium with Outlook 2002.

The problem is with ActiveSync saying the certificate is invalid.  I have copied the certificate to the pda to install and when I double click it, it says "Cannot access certificate."  It is a self generated certificate.  I have looked high and low for resolutions and I have found many references to disable the certficate lookup but all are for older versions of PocketPC such as certchk.  I did read somewhere about modifying the registry but have been able to find exactly what I am suppose to modify in the registry.  Any Advise would be appreciated.

Oh, and OWA works just fine on it (PDA) and gives the certficate screen and lets me proceed without problem.

    Well I answered my own question with enough determination.

    I tried re-creating my server certificate and that did nothing different for me.  What finally wound up working was opening mmc and adding certificates as a snapin.  Then you can go into the properties and export the certficate.  I exported it as a DER *.cer file and copied that to the PDA.  Then when I clicked on it, it asked me to install the certficate and bam, everything worked after that.  Tried it wirelessly on a seperate wireless internet connection and syncs up right away.

    I thought about deleting my post since its mine but thought it might be helpful to someone else.  Its up to the administrators what to do with it.
