Enterprise Contacts

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 iOS Contacts 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 • Always current — syncs automatically in the background, about every 2 hours, without opening the app; sync by hand any time • Contact photos — profile photos from Microsoft 365 are downloaded and stored locally • Privacy first — contacts are stored on your iPhone only and never sent to us or anyone else; optional usage data contains no contact information • Demo mode — explore the app with sample data before connecting your account REQUIREMENTS • An 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) FOR IT ADMINS Enterprise Contacts is a multi-tenant app available in the Entra ID Application Gallery.
