Sync contacts across devices?

Question

Android

There is a need to synchronize contacts (address book) between several devices (Android, Desktop, Windows Phone).
I used to use a LiveID account, but after updating the physical devices on the anroid, the contacts from the live.com account are no longer synchronized on the new one.
Interested in a self-hosted solution and an application for mobile devices (Although an android - vinfon can be periodically updated manually) and support for any Windows client (better of course, standard contacts or Thenderbird), but you can also have your own client.
Zimbra was a good option in theory - but AD support is only there in the paid version.
I really want an opensource or free version (the server part does not matter under which OS, it is desirable that it requires up to 8GB of RAM).
Will someone tell?

Answer 1

I installed Kolab as a simple alternative to Exchange - everything is OK in sync.

Answer 2

on Win 10 (1803) the People application was added, it pulls contacts from different sources and is quite correct.
For Iphone and Android tablet I use gmail account. Or I didn't understand your question.
