Office 365 Global Address Lists on Every Business Smartphone

Always Synced. Anytime. Anywhere.

No Credit card. No Contract.

Office 365 does not automatically sync Global Address List contacts to smartphones.

Fixing the missing sync is not simple or easy

Manual workarounds for syncing contacts, calendars, and notes to smartphones are error prone and time consuming. Custom apps are not scalable or have limited functionality.

Loss of productivity and revenue for business users

Without an automatic Office 365 GAL sync solution, employees waste time looking up current contact information, are unable to identify critical business calls, or are forced to make manual updates.

A Secure SaaS Platform for Automated GAL Sync is Vital for Business Growth.

The CiraSync platform provides centralized administration with single sign-on, granular control, and best-in-class support. No software to install, no client configuration, and no need for user training. It just works.
