contact picture Synchronisation Mac / Android

[Hirsch Ferkel]

Hi zimbra-forum,

we use zimbra to sync between iphone / android / mac. When i try to add profile-pictures to adressbook accounts in zimbra-desktop or with the online zimbra interface, all added pictures will be deleted within some minutes after servers have refreshed all clients.
But when i add pictures to contacts with my android mobile they will never more be removed and stay fixed in all client adressbooks, even after synchronisation.

So does anyone know, why i can add pictures to contacts by mobile, but not with zimbra desktop or even not with the synchronised mac-adressbook?

Thanxs for your help, hirschferkel
