What Our Customers Say

Frequently Asked Questions

Can Android devices sync directly with Active Directory?

Android devices have no native ability to connect to Active Directory, which means organizations need a dedicated sync solution like CiraSync to automatically deliver directory contacts to Android users.

Is the Global Address List the same as Active Directory?

The GAL and Active Directory are related but not the same — Active Directory is the authoritative directory of users and attributes, while the GAL is the contact list Microsoft 365 and Exchange surface from that data for email and search.

Why do contacts show up in Outlook but not in Android Contacts?

Outlook accesses the GAL directly from the server, but Android Contacts only displays what has been explicitly synced to the device — CiraSync closes that gap by automatically pushing GAL contacts to Android

Can Mobile Device Management tools handle contact sync well?

MDM tools are built for device security and policy enforcement, not contact synchronization, so organizations that rely on them for GAL sync often find themselves with incomplete, outdated, or inconsistently delivered contacts across devices.
