How to use Outlook addressbook and calendar with mailboxes hosted in Plesk?

Answer

Starting with Plesk Onyx 17.5, Plesk Premium Email (powered by Kolab) extension can be used for this purpose.
This extension offering all variety of shared options including calendars, mail lists, addressbook etc.

Kolab recommends using ActiveSync to synchronize Outlook 2013 or later with calendar and contacts (for older versions check this article):

In Outlook click File > Add Account.
Select Manual setup or additional server types. Click Next.
Select Outlook.com or Exchange ActiveSync compatible service and click OK.
Fill in the information. Make sure to use webmail.example.com as the mail server.
After the Kolab contact is synced, Calendar and Contacts will be available.
In order to enable synchronization, review ActiveSync settings in the webmail client: Parameters > Activesync > select Outlook client.
