Buyer-intent guides for Microsoft 365 contact sync
Microsoft 365 contact sync means copying users from Microsoft Entra ID into Exchange Online mailbox contacts, so every employee's phone shows a name for each colleague. These guides cover the two most common goals: replacing EWS-based sync scripts and getting Entra ID contacts onto iPhone and Android.

A practical guide for turning Entra ID users into real mailbox contacts so names show up on company phones.

Questions about these guides
Which guide should I read first?
If you already run a PowerShell or EWS script that writes contacts, start with the EWS replacement guide. If your employees see unknown numbers because directory users never reach their phones, start with the Entra ID phone contacts guide.
Why can't the Global Address List replace phone contacts?
The Global Address List is searchable in Outlook, but its entries never appear in the native contacts app of iPhone or Android. Without real mailbox contacts there is no caller ID and no name in the dialer or in messaging apps.
Does CYNC still use Exchange Web Services?
No. CYNC reads users and writes contacts only through the Microsoft Graph API, so the EWS retirement in Exchange Online does not affect it.
Need a quick path to production?
Start with the installer and follow the setup docs for your first sync.
