Sync Microsoft Directory Contacts to Phones in About a Minute

One change shouldn’t create three versions of the truth.

A customer’s phone number changes. Your CRM has the new number, Outlook still has the old one, and an employee’s phone has an even older number saved manually.

Employees risk calling the wrong number or not recognizing incoming calls. IT is left figuring out which record is current and fixing the rest.

ONE CONTACT. THREE SYSTEMS. THREE DIFFERENT ANSWERS.

AND THE CHANGES DON’T STOP

People join, change roles, and leave. Businesses add systems, environments, and entire companies. Every change creates another chance for contact and calendar information to drift.

Keep contacts and calendars current, regardless of your setup.

Across systems, between Microsoft 365 environments, and out to the places people actually work, CiraSync keeps contact and calendar information current where it needs to be.

From systems to people

Keep directory and CRM contacts current in the native contacts app on employee phones so incoming numbers resolve to names instead of questions.

Every connector on your terms.

Set the source, destination, and direction for each Connector. Choose which source takes priority when information conflicts. Use one-way sync to send updates in one direction, or two-way sync when changes need to flow both ways. Once the rules are set, future updates follow the configured flow.

Add new systems.
Not new projects.

As your business gets more complex, your integrations don’t have to. Bring new systems to your CiraSync setup without rebuilding the sync flows already in place.

Cloud when you want it. On-prem when you need it.

Run CiraSync as a managed cloud service, or deploy it in your own environment when privacy, infrastructure, or data-location requirements call for more control.



Cloud

CiraSync hosts and manages the service.



On-Premises

Run CiraSync inside your own environment for more control over infrastructure and data location.

Reliable sync should run quietly in the background.

CiraSync is built to run quietly in the background. As your environment changes, the flows you’ve configured keep running. When something needs attention, adjustments are easy to make. If you need a hand, our support team will help.

The proof is in what IT gets back.

12–25 hours of busywork eliminated every month.

This software is one of those ‘best things since sliced bread.’ We have eliminated probably 12–25 hours a month of somebody doing busywork maintaining contacts to push out to mobile devices.

Once it is set up, it flows seamlessly.

I have used this software across multiple companies. It works well for what it does and solves the issues of having to copy contacts to users’ Outlook profiles. Once it is set up, it flows seamlessly.
