Open-Xchange Contacts synchronization with CardDAV

This site describes how the Open-Xchange server can be accessed via its CardDAV interface after the server has been configured as described in Caldav_carddav_Bundles. Depending on the used client software, different steps are necessary. Other clients may be configured similarly, but are not officially supported.

Mac OS X Address Book / Contacts

Depending on the used Mac OS X version, slightly different steps are necessary.

Mac OS X Contacts

  • Choose "Contacts" -> "Add Account..." from the Contacts App main Menu
  • In the "Choose Contacts Account Provider..." Menu choose "Other Contacts Account..."
  • In the "Add a Contacts Account" Menu choose "CardDAV" and "Account Type" "Manual"
  • In the "User name" field enter your username
  • In the "Password" field enter your password
  • In the "Server address" field enter your server address with the prefix "dav." (e.g. "dav.myserver.tld").
  • Click "Sign In"

PLEASE NOTE: For our product Open-Xchange Server Edition for UCS it isn't necessary to use "dav".

Debug Options

You can enable a Debug Menu inside the Address Book application which gives you access to advanced debugging and logging options. Please notice that some of these options may increase the size of the log files of your system and/or could also log sensitive data like passwords if enabled. Keep also in mind that any setting changed here will remain active until the setting itself will be reverted or changed again which means that disabling the Debug Menu itself is not sufficient to reset any debug settings to their defaults. All settings are case sensitive.

Open a terminal window (Applications > Utilities > Terminal) and issue the following command for

  • enabling the Debug Menu in the AddressBook:
defaults write com.apple.AddressBook ABShowDebugMenu -bool true
  • disabling the Debug Menu in the AddressBook:
defaults write com.apple.AddressBook ABShowDebugMenu -bool false

PLEASE NOTE:: The debug menu is not available in Mac OS X 10.8.


iOS Contacts

The iOS Contacts application on the iPhone, iPod or iPad can be configured as follows.

PLEASE NOTE: For our product Open-Xchange Server Edition for UCS it isn't necessary to use "dav".
