How to upgrade kopano to 8.7.0




I am running the latest updates on Univention Corporate Server and Kopano I am seeing the problem when using Outlook 2016 and the OLE Client where some emails in Outlook are empty. I have read that there is a bug found in and this problem is fixed in a later release of Kopano. I am running the community edition, i have performed all updates but nothing shows to upgrade to the later version of Kopano which will hopefully then fix the problem.

I used the app center to install Kopano originally, is there a way if -:

There is a manual fix


How can i try and upgrade the version of Kopano as other users have posted it has solved the problem.

any help would be appreciated.
