Shared address book?

Question

Outlook

Good day.
I looked around a lot of resources, but I did not find anything sensible.
There is a Zimbra OSE. it has the ability to pull contacts.
There are users both inside the local network and outside it, they mainly use Outlook, but there are some with mozilla.
How can you organize your address book.
It is desirable that it be unloaded from hell to the host, and from the host all clients pull it up.

Answer 1

I am using the Addressbooks Synchronizer and ThunderBird plugin. On one computer, it is uploaded to a shared local resource, and other PCs are taken from this resource.
For clients from the outside, this file can be synchronized in some way and pulled up by the mailer.
