Calliente – Synchronization of Microsoft 365 Contacts on Mobile

Calliente is a simple and lightweight mobile application that automatically synchronizes contacts from Microsoft Entra ID (formerly Azure Active Directory) into the native Contacts app on smartphones.

It is aimed at organizations using Microsoft 365 that want their users to have up-to-date professional contacts on their phones, without complex setup or special maintenance.

What is Calliente for?

The goal of Calliente is clear: to make professional contacts accessible and usable directly on mobile.

Specifically, the application:

securely connects to the Microsoft 365 tenant via OAuth 2.0
retrieves users from the Entra ID directory who have a phone number
synchronizes this information into the native Contacts app on iOS and Android
on Android, saves contacts in the professional profile to ensure a clear separation between personal and professional data

Why use it?

In many organizations, contacts already exist in Microsoft 365… but are not available on phones.
Calliente simply fills this gap.

It notably allows:

immediate identification of incoming calls
avoidance of manual exports, scripts, or CSV files
operation without elevated administrative rights
use on both Android (professional profile) and iOS
deployment via Microsoft Intune or use on unmanaged devices

For whom?

Calliente has been designed for:

IT teams looking for a reliable and easy-to-deploy solution
employees who are often on the move, for whom the phone is an essential work tool
companies using Microsoft 365, especially for field teams, sales, support, or management profiles
