What program to use for general contacts?

Question

Android

At work, very often there is a need to exchange contacts (e-mail phones), maybe there is some kind of ready-made solution. Several people install a program on their phone, in which if a person gives access to a certain contact, then this contact appears for the rest who have this program installed. Something like a general phone book. Now we use shared cloud storage, which is very convenient. And I would like something similar with contacts. Naturally, the main thing is to carefully share contacts.

Answer 1

exchange server. "General address book".
But in general this is a very common solution.
