GALsync – Synchronize address lists and objects in Exchange & Active Directory environments


Do you have more than one Active Directory forest and want to exchange information in your Exchange Global Address List? Have you been tirelessly searching for a simple and cost effective way to solve your problem? Well we are happy to let you know that your search is over!

GALsync is an easy to use and cost effective solution that allows you to share Exchange mail-enabled objects between forests.

Usability Scenarios

  • Multi-Forest Company Deployment
    Your company has one internal Active Directory and one separate Active Directory for company’s sales representatives. You want all user objects and groups of the sales reps AD to be visible to your internal Outlook/Exchange users (using the Global Address List). Vice versa: You want all sales reps have access to information of a subset of the internal users.

  • Company take-over
    Because of a company take-over you have to integrate different Active Directories and Exchange organizations. You have to share all or subsets of all user and group information for Outlook/Exchange users in the Global Address List.

  • Company & Partner
    Your company has a partner company and you want to share some user and group information for Outlook/Exchange users in the Global Address List.

  • Migration
    Your company wants to migrate to a new Exchange organization. You have to ensure that all migrated users may send messages to users in the original organization and vice versa.

Program functionalities

  • Choose the objects you need
    You can select all objects or subsets of objects to export to the other AD. While GALsync is used for Outlook/Exchange it will only consider mail-enabled objects. Additionally you can exclude objects by using an configurable phrase in a configurable custom attribute.

  • Free Busy Sync
    Do you need view a GAL from another company? GALsync quickly and easily enables your organization to sync free busy information between Exchange 2003, 2007 and 2010 organizations.

  • Multiple-Domains
    GALsync is cross-domain capable. Simply select objects in any of the domains in your forest to export..

  • Choose your Transmission Protocol
    GALsync allows you an integrated handing-over of the selected information to the other Active Directory by using a Windows Share, by FTP or by SMTP.

  • Secure data transmission
    Data is transmitted encrypted between the different Active Directories, So nobody can read your object’s details during the transmission from source to target.

    While Exporting your information you create a secure key which has to be sent separately to the administrator of the other side. Only with this secure key he may import the data.

  • Managed Code
    GALsync is written in managed code using .NET framework. It may run on 32 or 64bit Windows platforms.

  • Log Files
    Log files are created so you can track exactly what happens. If you want the warnings and error messages also to be written to the application log you may configure this as well as different protocol and severity levels.


  • Export information from your forest by selecting objects and their attributes.
  • Import information from another forest and publish them in your Global address list (GAL).

  • Transmit data in a secure manner.

  • Configure an export and import schedule.

  • Reduce time and failures caused by sharing information manually.
