One source, many recipients: How efficient GAL Sync works
The Global Address List (GAL) is a central contact source in Microsoft Exchange. However, Microsoft does not offer an integrated option to automatically synchronize these contacts to multiple users' mailboxes at the same time.
sync.blue® closes this gap: You connect your GAL once, and sync.blue® automatically synchronizes the contacts it contains to the personal Exchange mailboxes of the desired users.
No exporting, no tinkering, no additional software installation. Simply automatically synchronized contacts for all employees.

Experience automatic GAL Sync with Microsoft Exchange – simple, secure, and available everywhere with sync.blue®

Your global address list in Microsoft Teams
Up-to-date contact details are essential in everyday business life, whether at your desk, in your home office, or on the go. However, employee contacts are often scattered across different systems or not always kept up to date. This means that phone numbers, email addresses, or roles are missing when they are needed.
With sync.blue®, the company-wide global address list (GAL) from Microsoft Exchange is automatically synchronized with smartphones such as iPhones and Android devices. This means that all important contacts are available centrally and up to date in the native address book – regardless of device or location.
This means:
-
No individual manual setup by IT
-
Intelligent caller ID
-
Access to phone numbers, email addresses, and roles – anytime, anywhere
-
Faster availability and smoother collaboration across the entire company

Find, call and recognize contacts in Teams
Outlook is the central tool in the daily work routine for many employees. With sync.blue®, GAL contacts are automatically synchronized to your users' Outlook mailboxes.
This means that all employee contacts can be viewed and used directly under “Contacts” in Outlook – even in the Outlook desktop applications. All data remains up to date at all times, without any manual exports or duplicate maintenance. Distribution is targeted at individual users or entire groups, for example in branches or project-based teams.
This means:
-
Automatic synchronization of the GAL in Outlook
-
Central maintenance, hourly updates, no manual imports
-
View and use directly under “Contacts,” even in desktop applications
-
Can also be used on smartphones, including caller ID
