Auto-sync Microsoft 365 Contacts across your Orgs Phones
CYNC is a Windows Service that automatically syncs Microsoft 365 contacts to every user's Outlook address book and Phone Contacts using Microsoft Graph — no scripts, no manual exports. Install via MSI, connect to your tenant with certificate-based auth, set your sync schedule, and forget about it. When someone joins or leaves, everyone's address book updates automatically. Free for teams under 10 users. Volume-tiered pricing for larger orgs. Self-service subscription management included.
