When you try to add Kerio or iCloud (formerly known as MobileMe) email accounts to your Surface device or to Windows Phone 8, Windows RT, or Windows 8, you may experience issues. This article describes those identified issues and their workarounds.

More Information

Before you follow these steps, make sure that your device is running the latest updates. Check Windows Update for any available Windows updates, and check for mail app updates. Mail app updates are available from the Microsoft Store.

Kerio mail on Windows 8 or Windows RT

A Kerio email account requires you to import a mail certificate. You can find the location of the certificate from the mail server settings options. From there, you can download your own personal certificate.

Note If you are not sure how to do this, ask your mail administrator for help.

  • When you download the certificate, select the Local Machine option, and then complete the User Account Control (UAC) credential popup request.

  • Manually select where you want to keep the certificate, and then select Trusted Root Certificate store.

  • Select this folder, and then tap OK. You should now be able to connect through SSL by using the correct server addresses in Settings on the Settings page.

If you are unsure about any settings, contact your mail administrator.

Kerio mail on Windows Phone 8

You do not have to import a certificate for Windows Phone 8. However, you have to make sure that your settings are correct and that you are using a valid account.
