How CiraSync Syncs Azure Active Directory to Smartphones
CiraSync connects directly to your Microsoft 365 account, extracting contact information from your Azure Active Directory (Entra ID) and syncing it to designated smartphone devices based on your configured settings. From there, the sync runs automatically on your preferred schedule with no helpdesk tickets and no user complaints about missing or outdated contacts.
Key contact fields including name, email, phone number, and job title map automatically to the native contact apps on both iPhone and Android. No field-mapping configuration needed on your end, and no cleanup needed on the device. CiraSync handles duplicate and conflict resolution before anything hits the phone.
Sync Your Active Directory To Any Phone In Minutes
The CiraSync dashboard gives IT full visibility and control over sync operations across your entire organization. Because CiraSync works directly with Azure Active Directory (Entra ID), your contact data is always sourced from the same directory your team already manages with no duplicate data entry, no separate directory to maintain.
Use your existing Microsoft 365 distribution lists and security groups to control exactly which contacts sync to which users. No new group structure to build or maintain. Set sync schedules to run hourly, daily, or on-demand for situations that can’t wait, like an org restructure or an executive contact change.
Real-time monitoring and detailed sync reports show exactly which devices were updated, flag any failures, and give you the audit trail you need for compliance reviews.
CiraSync is SOC 2 certified and GDPR compliant, with full audit logging of every sync event — so your security team has the documentation they need and your data never leaves your Microsoft 365 environment.
Active Directory Sync That Scales With Your Company
Every missed call or meeting is a lost opportunity. CiraSync eliminates that risk by ensuring your team always has up-to-date contacts when syncing Active Directory to smartphones. It’s more than just a contact update—it’s a smarter way to stay connected and keep business moving.
With CiraSync, you’re not just syncing contacts—you’re staying ahead.

Loved by IT Teams and C-Suites Everywhere
CiraSync is the functionality Microsoft 365 should have built in.
“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.”
Ed H. Senior Network Administrator/ IT
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, if flows seamlessly.”
Matthew M. IT Director
CiraSync, always available information, on- or off line.
“CiraSync is our solution to mainly sync contact information to our organization’s iDevices. Rather than depending on a Global address list (which is not really fast in delivering information), CiraSync pushes information, on- or off line. We are happy customers.”
Eddy K. Facility Manager & IT
