  • Sync return HTTP_400

    Hi,

    I have windows server 2003 running with Exchange 2003 SP1. Also i have an IPAQ with windows mobile 2003. It was possible to sync this ipaq with oma on the exchange server, also i managed to use ssl, everuthing was OK.

    then i installed sharepoint server, then it was not possible anymore to sync the ipaq (HTTP_500 error), i deinstalled the sharepoint, still the HTTP_500. Now at this time i still get the HTTP_400 error.

    i think it has something to do with kerberos (?????), how can i manage to let the sync proces use the kerberos protocol again.

    thanks in advance

    regards henk

    Any reason you are not on Exchange 2003 SP2?
    The way that ActiveSync worked was changed in that service pack and I would suggest that you upgrade the server first before continuing.

    Once you have upgraded the server, does oma work?

    https://host.domain.com/oma

    OMA and ActiveSync share a similar backend, so if one works the other will. However OMA is much easier to troubleshoot.

    If when you browse to OMA you get a certificate prompt, then ActiveSync will not work.

    Are you using Forms Based Authentication as well? If so there is a known issue with FBA, SSL and ActiveSync which is discussed in KB 817379 or my article at http://www.amset.info/exchange/mobile-85010014.asp

    However before making changes to the server I would suggest updating it to the latest patch level.

    Simon.
