Error with self-signed certificate: Unable to sync Windows Phone

Hi,

Please find information below which may help you with your concern in syncing your Windows Phone to your Zimbra account because of the self-signed certificate. For this specific concern, you must import the root certificate from the server into your device. Kindly follow the steps below:

1.       You need to go to: /opt/zimbra/ssl/zimbra/ca directory and you need to copy the ca.pem file to a safe location.

2.       You need to use this codes and run on the file you copied:

$ openssl x509 -in ca.pem -inform PEM -out MyCertificatecrtcer -outform DER

3.       Now, you may need to copy the new MyCertificatecrt.cer file to your Windows Phone.

4.       With the use of your phone’s File Manager, you can now click on the MyCertificate.crt file and you should receive a message that it was successfully imported to your device.

5.       Lastly, you need to enable SSL in ActiveSync on your phone.

I hope this finds you well.

To sync a Windows phone with a Zimbra account, on your Windows phone, tap “Start,” “Programs,” “ActiveSync” then tap the “set up your device to sync with it” link. Next, tap “Add Server Source” then enter your Zimbra server address. This is the publicly accessible hostname of the server like for example, without quotes “zimbra.example.com”.

If SSL is used like when the server’s zimbraMailMode is “https,” “redirect,” or “mixed,” check “This server requires an encrypted (SSL) connection” then tap “Next.” Enter your User name, Password, and Domain. Check “Save password” then tap “Next.” The “User name” is the username of your Zimbra account and the same username you used to log in to the Zimbra web client.

For example, without quotes “[email protected]”. The “Password” is your Zimbra password and the “Domain” is your company’s email server domain like for example, without quotes “mail.company.net”. When you are finished, tap “Next.” On the next screen, check the items you want to synchronize like Contacts, Calendar, E-mail, and Tasks then tap “Finish.”
