Installing a Self-Signed Certificate on a Pocket PC device
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Providing that your mobile device allows you to install self-signed certificates, you can copy certificates to your Pocket PC device by using ActiveSync or Windows Mobile Device Center (WMDC), and then use the Certinst utility to install the certificates. The example below uses ActiveSync. The procedure for Windows Mobile Device Center is very similar.
To install a self-signed certificate on a Pocket PC device
Connect your mobile device to the computer running ActiveSync and verify that ActiveSync is showing a connection to the mobile device.
Do one of the following:
If you are using a computer running Windows Vista, open Windows Mobile Device Center, click File Management, and then click Browse to view the contents of your device.
If you are using a computer running another Windows operating system, open ActiveSync, click Explore, and then double-click My Windows Mobile-Based Device.
Copy the certificate from your computer or from the network location where the certificates have been saved to a folder on the device.
On the mobile device, use File Explorer to go to the location where you copied the certificate.
Tap the certificate to run Certinst, and then tap Yes to install.
