How to install Microsoft Azure Active Directory Sync Services

Share this:

How to deploy the Microsoft Azure Active Directory Sync Services (AADSync) released in the last September, keep in mind that DirSync is still supported. In the future, seems that we will have only Azure Active Directory Sync Services due its new capabilities such as: multi-forest synchronization, AD attribute filtering, multiple on-premises Exchange Organizations mapping a single AAD tenant and so forth.


If you are happy with DirSync there is no requirement to upgrade, but if you are deploying a new environment the AADSync can be a good fit.

Downloading Microsoft Azure Active Directory Sync Services…

In order to install the product, let’s download it from here:


Deploying Azure ADSync…

After downloading and executing the installer, the first page will be the Welcome page which brings the license terms and the installation location. Let’s leave default settings and click on Install.


In the Azure Credentials page. Let’s type in the service account information created previously on Microsoft Azure and that account must have Global Administrator privileges.

More information how to create it:


In the AD DS Credentials page. Type in the information to access your forest, after that click on Add Forest


In the same page, we have the ability to add additional forests in case we want to and that is one of the key features of Azure ADSync Service tool. In our case we have just one, and we will click on Next.


In the User Matching page. How we are going to identify our users, let’s leave default settings and click Next.


In the Optional Features page. Here we can define optional features, such as if the environment will support Exchange Hybrid deploy, password synchronization and so forth. Enable all features that you are planning to enable and click Next


In the Configure page. Check the information that we have configured so far, and click on Configure.


The final page will have the option Synchronize now enabled by default, click on Finish and wait for the replication to take place with Microsoft Azure.


One last step to complete the deployment of the tool is to logoff the current session.
