Identities have nothing to do with default address books or address 
book synchronization prefs.

Please use mailing list for further support if needed, as this is not a bug.

Ok, overridden all User Config to "Default" now it's running again.
i don't undestand why there is a difference between "Default identity" 
and "Use Default"

Not sure what this was supposed to show...webdav has nothing to do 
with ActiveSync.

It's possible your sync addressbook pref and/or default address book 
pref is incorrect/corrupt. Try resaving these prefs and see if it helps.

Since you say Turba->Client works and editing existing from 
Client->Turba works, pleae verify that you are adding the new contact 
to the correct account type on your device.

Otherwise, there is really nothing we can do without the requested sync log.

Actually i've only a prod. server

but i've also tested this issue with an iPad (latest iOS)

i've created a new contact but nothing is pushed into Horde contacts

To further debug this issue, we need details of the Horde -> Device 
connection. It may also be beneficial to obtain a network capture.

To enable debugging, see instructions contained in the ActiveSync 
section of Horde's configuration. Also, see 
http://wiki.horde.org/ActiveSync for more details.

Debugging should not be enabled on a production server,   Attach/post 
only the portion of the log that directly deals with the problem 
reported (it may be simplest to clear the log file and then perform 
the event that causes the error).

When i create a new Entry on my Phone (Android .5.1.1)
this new entry is not published / pushed to Horde / Turba

If i create a new Entry in Turba, the entry is published to my phone

if i update the entry on each side the updates are published to each other.

is this a bug or is this "normal" ?

i'm nor sure but i think to know, that some versions before all new 
contacts are well published to Turba.


Thank You
