Integrating IMAP/CalDAV/CardDAV Accounts with Kerio Connect on iOS Devices

Author: Central KB Updated

Overview

This article explains the process for synchronizing IMAP (Internet Message Access Protocol), CalDAV, and CardDAV accounts on iOS devices with the Kerio Connect account.

  • IMAP (Internet Message Access Protocol) is a standard email protocol that stores email messages on a mail server.

  • CalDAV is an Internet standard allowing a client to access scheduling information on a remote server.

  • CardDAV is an address book client/server protocol designed to allow users to access and share contact data on a server.

Process

Note: This feature does not work on iOS15. This is due to a restriction imposed by Apple from this OS version, requiring that each payload in a configuration profile must contain a unique PayloadIdentifier. Since such profiles do not have unique identifiers, you will get an error message such as:

In (at least) some iOS 14 versions, the profile downloads; however, the personal certificate is not imported and cannot be imported manually later on either. Therefore, if you are using either iOS 14 or iOS 15, it is recommended to configure the profile "manually" if you wish to encrypt and sign your emails. 

For other versions:

  1. In your Safari browser, enter the URL address of Kerio Connect server.

  2. Tap the Integration with device button.
