Hai, I did have a look at this and this report is missing a lot what we need to determin the problem. The installed packages does not show mariadb-server installed. Is this kopano setup connecting to a remote store when you tested? from the server.cfg # drop privileges and run the process as this user run_as_user = kopano # drop privileges and run the process as this group run_as_group = kopano These are the default and is not needed to enable it. After removing kopano there are some left overs, after upgrading from 8.5 to 8.6 a simular problem. ( with the kopano community packages ). https://forum.kopano.io/topic/1305/crash-kopano-core-upgrade-from-8-5-81-288-0-53-1-to-8-6-80-645-0-68-1/12 https://jira.kopano.io/browse/KC-1138 shows fixed in 8.6.2 and 8.7.0 If it was an upgrade, remove and purge kopano, check for left overs, remove them and install again. My test showed. dpkg: warning: while removing python-kopano, directory '/usr/lib/python2.7/dist-packages/kopano' not empty so not removed ls -al /usr/lib/python2.7/dist-packages/kopano total 60 drwxr-xr-x 2 root root 4096 Sep 14 09:48 . drwxr-xr-x 5 root root 4096 Sep 14 09:48 .. -rw-r--r-- 1 root root 6422 Sep 14 09:45 compat.pyc -rw-r--r-- 1 root root 7498 Sep 14 09:45 config.pyc -rw-r--r-- 1 root root 1757 Sep 14 09:45 errors.pyc -rw-r--r-- 1 root root 5537 Sep 14 09:45 __init__.pyc -rw-r--r-- 1 root root 5958 Sep 14 09:45 lru_cache.pyc -rw-r--r-- 1 root root 8407 Sep 14 09:45 utils.pyc -rw-r--r-- 1 root root 169 Sep 14 09:45 version.pyc

Kopano in debian is what i wanted for a long time so i'll help out what i can. im not a coder, but im working with kopano (zarafa) since 4.x. Greetz, Louis
