Smooth communication is crucial in modern companies - especially when employees are on the move or working with a smartphone. One problem that is often underestimated is the lack of access to an up-to-date global address list (GAL) on mobile devices. But this is exactly where a GAL Sync Tool for Android and iOS comes into play.
To give you the best introduction to the topic, we answer the most important questions about mobile GAL synchronization in this article:
Frequently asked questions:
What is GAL?
What does the abbreviation GAL stand for?
How can I display the Global Address List (GAL) on my iPhone or Android smartphone?
Is there a way to automatically synchronize Exchange contacts with the company cell phone?
Which solution is GDPR-compliant and suitable for mobile GAL synchronization?
How can employee contacts be managed centrally and transferred to mobile devices?
What is the GAL?
The abbreviation GAL stands for Global Address List. It is a central address book within Microsoft Exchange or Microsoft 365, in which all email addresses, telephone numbers and contact details of a company are stored. The GAL makes it possible to find all company contacts quickly - however, it is only available on desktop applications such as Outlook by default.
To ensure that GAL is also available on mobile devices such as iPhones or Android smartphones, a GAL Sync Tool is required that automatically transfers the contacts to the respective device.
Why a GAL Sync tool for mobile devices is indispensable
Without centralized address management, employees are often forced to store contacts manually - a risky and inefficient process. A mobile address book for teams that is automatically synchronized not only saves time, but also ensures GDPR-compliant contact management.
Especially in larger organizations with many departments, it is important that everyone has quick and easy mobile access to the company address book. Whether new colleagues, changed extensions or department changes: with a reliable tool for GAL synchronization, all information is always up to date - even on the iPhone or Android company cell phone. This allows you to call employees directly via the iPhone or Android device without having to save numbers manually.
Advantages of a central GAL Sync tool
A good GAL sync tool for Android and iOS should be able to do more than just transfer contacts. It should:
Synchronize company contacts automatically
Be available on the iPhone or Android smartphone
Fully support Exchange GAL
be easy to integrate into existing mobile device management systems
also offer a synchronized address book offline
and above all: work in compliance with GDPR
The result: an up-to-date, central employee address book that is identical on all devices at all times - without any manual maintenance.
