CYNC - Entra ID Contact Sync Service

Imagine a world where your organization's contact list is always perfectly up to date, everywhere your team needs it. That is the core promise of the 236. CYNC - Entra ID Contact Sync Service. We all know the headache of managing shared contacts: someone updates a phone number in the main directory, but half the sales team is still calling the old extension because their mobile contact list hasn't refreshed. CYNC eliminates this friction entirely by acting as a silent, reliable bridge between your Microsoft 365 environment and your users' devices. This isn't another clunky script you have to babysit; it’s a robust Windows Service designed for true set-and-forget reliability. Once installed via a simple MSI package, you securely connect it to your tenant using certificate based authentication—ensuring enterprise-grade security from the start. You define the schedule, and CYNC takes over, leveraging the power of Microsoft Graph to push those essential contact updates directly into every user's Outlook address book and, crucially, their native phone contacts. This means whether someone is in the office or on the road, they always have the correct, current information at their fingertips, dramatically improving communication efficiency and reducing costly errors caused by outdated data.

What truly sets CYNC apart is its seamless automation and low administrative overhead. Think about the time saved when employee onboarding or offboarding no longer requires manual contact list cleanup across dozens of devices or shared mailboxes. When a new team member joins, their essential contacts appear automatically. When someone leaves, their access is revoked, and their associated contact data is managed according to your policies, all without IT intervention. This continuous, automatic synchronization ensures that your operational data is always fresh, directly impacting productivity. For smaller teams, we believe in making powerful tools accessible, which is why the service is completely free for organizations with under ten users. For growing businesses, our volume tiered pricing ensures scalability without breaking the bank, and we include self-service subscription management so you stay in complete control of your service level as your organization evolves. CYNC is not just a sync tool; it is an essential piece of infrastructure that keeps your internal communication channels flowing smoothly and professionally, allowing your team to focus on what they do best, not managing address books.
