Gabsync outlook

Hi,

Maybe someone can help me?

I have configured zpush gabsync and the output looks good. My kopano mailserver is a diffent virtual mailserver.

the public store has read permissions. Still in outlook 2016/2019 the gab contacts or not showing.

My os is Debian Buster (10)
Kopano Core: 11.0.2

output from gabsync:

root@ex02:/usr/share/z-push/tools/gab-sync# ./gab-sync.php -a sync

Starting GAB sync to store 'SYSTEM'  on id '0bbd76ce78fe41d2b53a75a17452db650d6103000000'
