How to set up contact synchronization in Outlook 2016?

Question

Data synchronization

I have 2 PCs running Windows 10 (1803) with Outlook 2016 (Standard) installed. Working with a corporate mail server via IMAP/SMTP. In Outlook, I found the ability to attach an LDAP address book, but, as I understand it, support should be implemented on the server, but its administrator does not want / is not able to help.
How to set up online synchronization of the Outlook address book between these two computers (in fact, the stationary and mobile workstations of one employee).
