When Mobile Teams Lack Contact Access, Communication Breaks Down

Construction companies rely on real‑time communication—but field workers often lack access to shared contacts and calendars on their mobile devices.

Field workers can’t access GAL contacts on mobile devices
Caller ID doesn’t work for internal calls, leading to missed or ignored calls
Manual or legacy solutions fail after migrating to Microsoft 365

Automatically Sync Shared Contacts and Calendars to Every Device

CiraSync syncs Global Address List (GAL) contacts and shared calendars to user mailboxes and mobile devices. This gives field teams instant access to internal contacts, restores mobile caller ID, and eliminates the need for manual updates or IT intervention.

1. Create Sync Paths

IT selects approved shared contacts and calendars  

2. Determine Frequency
