Sync Effortlessly

Global Address List

Your employees are connecting on-the-go and in the field, where they need quick access to key contact information.

One source of truth for contact data, with industry leading compliance & security and proven reliability at any scale.

Calendars

While shared calendars are accessible in Outlook, employees also need smartphone access to stay updated. Without immediate access to current shared calendars on their devices, they risk missing important meetings, schedule changes, and emergencies. CiraSync seamlessly syncs these calendars to phones, ensuring employees are always in the loop.

CRMs

CRM licenses are expensive; however, not everyone needs full access to each application. Most employees only need access to contacts. For a fraction of the cost of a Salesforce license, CiraSync can automatically sync contacts to hundreds of employees smartphones.

Integrations

CiraSync integrates with Microsoft 365, Google Workspace and a variety of other platforms to automatically sync contact and people data across directories, shared mailboxes, and mobile devices – keeping information accurate and up to date without manual effort.

Why Your GAL Isn’t Syncing to Smartphones (And How to Fix It)

Many IT teams try to sync the GAL to smartphones only to find that Outlook updates never reach employee devices. This happens because Microsoft 365 does not provide a native way to sync the Global Address List to smartphones, which leaves users stuck with outdated contacts, manual exports, or one‑time imports that quickly become inaccurate. The most reliable fix is to use an automated contact sync solution that continuously pushes GAL updates to iPhone and Android address books without user involvement. This ensures every employee phone stays current, reduces support tickets, and keeps your organization’s contact data accurate across all mobile devices.
