Directory Synchronisation :


Address list synchronisation for Microsoft enterprises


Keep your company & partner organisations in touch.

Large organisations, those that have recently undergone mergers, or security conscious entities such as defence or financial institutions, often have multiple separate Microsoft Exchange environments.

This presents a challenge for email communication, as contacts from different Exchange sites do not automatically populate into everyone’s Outlook’s Global Address List (GAL).

Using our GAL synchroniser you can bridge this gap, giving users seamless access to contact information, but without connecting other aspects of the environment.


The benefits of using our directory sync tool

Streamline communications

  • Give staff in each domain the correct address details for contacting the relevant people
  • Ensure distribution groups have the right people in them
  • Trigger updates from multiple sources including HR & staff roster systems
  • Each party keeps their own directory – there’s no loss of ownership
  • Meet security or compliance requirements

The IT pro’s favourite dirsync tool

It’s incredibly easy to configure and can save months of effort working with Microsoft Identity Manager (MIM).

Technical teams love it as it doesn’t become the main directory and doesn’t create a central, master directory.

It simply synchronises directory information, so there’s no issues over politics or security, or maintaining yet another directory!

Due to this we have actually recommended it to our colleagues and clients as they have identified new requirements. This has resulted in an increased usage of the product within our department.”

Microsoft solutions provider partner

What our customers have to say

“We have recently merged with another company and we are both running our own domain/Exchange environments and are under increasing pressure to have all users appear in both companies (sic) address books. We were initially looking at using the Microsoft tool to do this, but after seeing what UnitySync can do, the solution looks a lot easier and would allow us to both keep control of our own environments.”

“The difference between this and the alternatives I’ve seen and used is that it makes the task of building a global directory very simple and straightforward…it didn’t disappoint.”
