Native iOS Contacts
No MDM required
Your company's contacts, right where you call from.
Enterprise Contacts pulls Microsoft 365 contacts directly into the native iOS Contacts app, so colleagues show up as caller ID, autocomplete in Mail, and appear in every app on your iPhone.
Encrypted on device. No third-party contact server.
Three audiences, one app
Built for the people who use it, the ones who curate it, and the team that owns it.

The flow
From Microsoft 365 to every app on the phone.
Authenticate once. Enterprise Contacts fetches contacts from sources you authorize, encrypts them on device, then publishes to the system address book where every other app reads from.

Native iOS integration
Delivered through Apple's ContactProvider framework, fully integrated with the system Contacts app, not a parallel address book.
Notification-based sync
Each contact source has a configurable notification schedule. When it's time to sync, the app notifies the user — no background server required.
Multiple contact sources
Sync from Entra ID security groups, shared Exchange mailboxes, or your personal Exchange contacts folder, all in one place.
End-to-end security
Authentication via Microsoft MSAL. Contact data is stored encrypted on device using iOS Data Protection. No third-party servers. Anonymous telemetry stays in the EU — Azure Sweden Central.
For IT administrators
Set up once. Works for everyone.
Configured entirely through Entra ID security groups. No MDM profiles, no app configuration files, no per-user setup.
