CalDAV

Mobility & Sync — ActiveSync, CalDAV & CardDAV

CalDAV is a protocol that allows clients to synchronize calendars and perform calendar scheduling actions.

The CalDAV service runs on top of WebMail; this means that the licence requirements for accessing the CalDAV service are similar to those required to access WebMail. Some of the CalDAV features, such as using scheduling features (accepting meeting invites, inviting other users to a meeting, etc) are subject to the restriction of the Axigen license (e.g. for scheduling to work a premium user license with a groupware add-on is required).

 

CalDAV support is available starting with Axigen X1.

How CalDAV works in Axigen

The CalDAV server built in Axigen maps the user's calendar folders (local calendar folders) to WebDAV collections (calendar collections).

A CalDAV client capable of performing collection discovery should be able to pick up the Axigen user's calendar collections as part of the CalDAV account configuration.

Supported clients

This section describes CalDAV clients that have been tested and have been found to work with Axigen 10.1. Some of the CalDAV features (e.g. scheduling for Windows Phone 10) are known not to work as the respective clients cannot fully interoperate with Axigen.
