  • Hi,

    1. Please verify that the Exchange & Root CA digital certificate didn't expired.

    2. Please verify that the server trust the root CA that was used to create the Exchange digital certificate.

    3. In case that you are using BlackBerry server please contact BlackBerry support.

    4. Exchange the Active Sync log and try figure who own the device (user_id=5017254?).

    The issue may occurred due no trust relationship with the root CA, old device settings in the ActiveSync/User Profile, compatibility issues, etc.
