Kopano-webapp apache error

Hi all,

I got apache errors in log file.

[php7:notice] [pid 14182] [client 192.168.2.4:52430] MAPIException: MAPI error  in /usr/share/kopano-webapp/server/includes/core/class.mapisession.php:584\nStack trace:\n#0 /usr/share/kopano-webapp/server/includes/core/class.mapisession.php(584): mapi_openmsgstore(Resource id #3, '\\x00\\x00\\x00\\x008\\xA1\\xBB\\x10\\x05\\xE5\\x10\\x1A\\xA1\\xBB\\x08...')\n#1 /usr/share/kopano-webapp/server/includes/core/class.mapisession.php(483): MAPISession->openMessageStore('\\x00\\x00\\x00\\x008\\xA1\\xBB\\x10\\x05\\xE5\\x10\\x1A\\xA1\\xBB\\x08...', 'Default store')\n#2 /usr/share/kopano-webapp/server/includes/notifiers/class.hierarchynotifier.php(144): MAPISession->getDefaultMessageStore()\n#3 /usr/share/kopano-webapp/server/includes/core/class.bus.php(237): HierarchyNotifier->update(32, 'dummy_value', NULL)\n#4 /usr/share/kopano-webapp/server/includes/core/class.jsonrequest.php(62): Bus->notify('dummy_value', 32)\n#5 /usr/share/kopano-webapp/kopano.php(145): JSONRequest->execute('{"zarafa":{"rem...')\n#6 {main}, referer: https://kopano/webapp/

What does this mean and how can i resolve this. Maybe this is causing some delays in loading webapp stuff. my mobile works fine.
