Contact, calendar, and directory syncing for hybrid, commercial, GCC, and GCC High environments

CiraSync On‑Prem, powered by Unified Contact Manager (UCM), synchronizes contacts, calendars, and Global Address List (GAL) across Microsoft Exchange Server and Microsoft 365 environments, including commercial tenants and Microsoft 365 Government (GCC and GCC High).

The solution runs entirely within the customer’s infrastructure and does not require a cloud service or third‑party data processing. This architecture supports organizations that require full control over data location, security boundaries, and operational access, including regulated industries and public sector organizations.


Core Functionality

  • Synchronizes contacts, calendars, and directory data to user mailboxes
  • Supports data sources such as Exchange public folders, shared mailboxes, and directory information
  • Provides consistent data availability across Outlook and Exchange‑connected clients
  • Automated, scheduled synchronization reduces the need for manual updates


Common Use Cases

  • Distributing Active Directory contacts and calendars to users
  • Synchronizing public folder or shared mailbox contacts and calendars into personal mailboxes
  • Maintaining consistent address list data across desktop and mobile clients
  • Synchronizing Active Directory data between two on‑premises environments, such as during mergers, restructures, or coexisting multi-forest scenarios
  • Supporting environments with heightened governance or compliance requirements


Deployment and Security Model

  • Deployed fully on‑premises within the organization’s network boundary
  • No reliance on commercial cloud services or external multi‑tenant infrastructure
  • No data stored or processed outside the customer‑controlled environment

Administration and Oversight

  • Centralized administration for configuration and monitoring
  • Granular control over synchronization scope, rules, and scheduling
  • Logging and diagnostic capabilities to support operational review and auditing
