Enterprise Contacts

Your Microsoft 365 contacts, always in sync — directly in the native iOS Contacts app. Stop searching. Start calling.

Enterprise Contacts keeps your organisation's directory always up to date — right inside the iOS Contacts app.

Once set up by your IT admin, Enterprise Contacts automatically syncs contacts from Microsoft Exchange shared mailboxes, Entra ID security groups, and your own mailbox directly to your iPhone. Every phone call, message, or search in the native iOS Contacts app will find the right person immediately.

KEY FEATURES

• Native iOS Contacts integration — contacts appear in the built-in Contacts app, Phone app, and Messages, with no extra steps
• Works with Microsoft 365 — uses your existing Microsoft account, no separate password required
• Multiple contact sources — sync from shared mailboxes, Entra ID groups, or your personal Contacts folder
• Set a background sync schedule to keep contacts up to date automatically — no need to open the app
• Contact photos — profile photos from Microsoft 365 are downloaded and stored locally
• Privacy first — contacts are stored on-device only; no data is sent to third parties
• Demo mode — explore the app with sample data before connecting your account

REQUIREMENTS

• iPhone running iOS 18 or later
• A Microsoft 365 / Entra ID account (provided by your organisation)
• IT admin must approve the app in your organisation's Entra ID tenant (one-time setup)
