we have a small team, which used to organize their work with tasks in Outlook. With Outlook 2010 and the mapi-client they used the features send and accept tasks and set different categories for tasks.
Now we switched to Outlook 2016 with KOE and set up a shared mailbox for the team and imported the tasks. We learned that no attachments for tasks are supported in ActiveSync 14. And that you cannot move emails between ActiveSync accounts. I also persuade them to not use the send/accept feature for tasks anymore.
Yesterday they reported that changes to their own tasks in Outlook won’t show up in Deskapp/Webmail. I looked at the logfiles and found several errors like:
06/12/2018 13:13:28  [ERROR] [michael] WBXMLDecoder->getElementEndTag(): could not read end tag in '/usr/share/z-push/lib/request/sync.php:533'. Please enable the LOGLEVEL_WBXML and send the log to the Z-Push dev team. 06/12/2018 13:13:28  [FATAL] [michael] WBXMLException: Unknown error in Sync->Handle() - code: 0 - file: /usr/share/z-push/lib/request/requestprocessor.php:117 06/12/2018 13:13:28  [FATAL] [michael] WBXML 10K debug data: ... 06/12/2018 13:13:28  [FATAL] [michael] Exception: (WBXMLException) - Unknown error in Sync->Handle() 06/12/2018 13:13:28  [FATAL] [michael] Request could not be processed correctly due to a WBXMLException. Please report this including the 'WBXML debug data' logged. Be aware that the debug data could contain confidential information.
We are running kopano 8.6.8 on CentOS 7.5.1804 with separate z-push-server (version 2.4.4) on CentOS 7.5.1804 (php 5.6 via software collection). The clients are 3 Windows 7 and 1 Windows 10 (1803) wiht Outlook 2016 and KOE 2.0.310.
Is the “WBXML 10K debug data” in the logfile sufficient to analyse the problem, where can I send it? Or do we need a full WBXML-log?Shall I update KOE to 2.0.331 and or z-push 2.4.5)?
