Microsoft-native
Authentication uses MSAL and contact sources come from Entra ID and Exchange.
About
Enterprise Contacts exists because company directories should work everywhere iOS already expects contacts to work.
The idea
Employees should not have to open a separate app to recognise a colleague calling, find a teammate in Mail, or start a Teams chat. Enterprise Contacts bridges Microsoft 365 and the native iOS Contacts system.
Product principles
Technical stance
Authentication uses MSAL and contact sources come from Entra ID and Exchange.
Contacts are published where iPhone apps already expect to find them.
No MDM profiles, no per-device setup, and no third-party contact server.
