If you are using high security settings on a Windows Mobile 6 device and have deleted the root certificates, you can manually reinstall them. There is no single archive or installer for all of the original root certificates, meaning you will have to download them all from their sources online. Once you have downloaded the root certificates (stored in the .cer file format), you can reinstall them manually to the Windows Mobile device.

    Perform Internet searches for all the original root certificates. These are the root certificates that were installed on the device:

    Class 2 Public Primary Certification Authority (VeriSign, Inc.)

    Class 3 Public Primary Certification Authority (VeriSign, Inc.)

    <p> Certification Authority (2048)

    <p> Secure Server Certification Authority

    Equifax Secure Certification Authority

    GlobalSign Root CA

    GTE CyberTrust Global Root

    GTE CyberTrust Root

    Secure Server Certification Authority (RSA)

    Thawte Premium Server CA

    Thawte Server CA

    Download these certificates when you find them. These should be in the .cer file format, but many may be compressed in zip archives. If they are, right-click the archive and click "Extract" to extract them.

  2. 2

    Connect the Windows Mobile device to the computer via USB. ActiveSync should automatically open; if it doesn't, launch it from the "Start menu." Click "Explore" in ActiveSync.

  3. 3

    Navigate, in a new window, to the downloaded .cer files. Select them and press "Ctrl"+"C" to copy them. Switch to the Windows Mobile window. Press "Ctrl"+"V" to paste them. Disconnect the device from the computer.

  4. 4

    Click "Start," on the Windows Mobile device, then "Programs," then "File Explorer."

  5. 5

    Locate the .cer files and double-click them. This installs the root certificates manually.
