Scalix CalDAV does not support Contacts or Tasks
Posted by - NA - on 30 June 2009 09:39 AM
Users operating on Scalix CalDAV protocol can only synchronize calendar PIM items.  The Scalix CalDAV protocol does not support synchronization of tasks or contacts at this time.

A work-around for pulling down contacts from the server to the device is to use remote lookup.  Additions of or changes to contacts or tasks made on the device, however, will not synchronize back to the server.
