Mails in Outlook 2016 no longer consistent after upgrade to Kopano Core 8.6.8.2

Once there has been a 8.7.1 release I will start working on an ucs update. We are still figuring out some stuff for the 8.7.1, though and at this moment I do not dare to make an estimate. I will be away on holiday starting next week, so its either this week or once i am back.
