How to Set up DirSync between Active Directory and Office 365

Office 365The following article outlines the steps required to set up directory synchronisation between a Active Directory (On-Premise) and Office 365 (Windows Azure Active Directory).

The screenshots in this post are from an Office 365 tenant that is on Wave 15 (i.e. the new version). If your organisation has yet to upgrade then some of the images may differ slightly.

The first thing we want to do is tell our Office 365 tenant that we are going to setup directory synchronisation. This can take some time, so best do this step first.

1. Log into Microsoft Online Portal

2. Select the Users and Groups button within the Office 365 admin center.

3. On the right-hand page select Active Directory Synchronization set up

4. Select Activate under Step 3, Activate Active Directory Synchronization.  Please note that this can take up to 24 hours to complete.

These credentials are not saved.

21. The Hybrid Deployment page, if used, provides a unified email experience for you Office 365 and on-premise environment. A Hybrid deployment boasts features such as unified GAL, off-boarding and others. A full list of these can be found here.

This requires an Exchange 2010 server on-premise, as we don’t have one for this setup, this is greyed out.

22. Password Synchronisation. The Sync’ing of password from on-premise to cloud allows users to access Office 365 with the same password as the one they use for on-premise resources. If you require this then select Enable Password Sync, and click Next.

Monitoring and Testing Directory Sync

Once you have the dirsync tool installed we will need to test that it works correctly. There are a couple of ways you can test and monitor dirsync, ideally what we want to do is test both forced & automatic updates.

To monitor our changes we can use the Synchronization Service Manager tool, which ships with DirSync.

Navigate to the following directory on the member server you installed the dirsync tool C:\Program Files\Windows Azure Active Directory Sync\SYNCBUS\Synchronization Service\UIShell

Double-click miisclient

To summarize, in the top frame you have a list of when dirsync ran, the bottom left frame gives you finer detail of the changes, for example the number of changes, add, deletes, etc.

To test a forced sync, navigate to you on-premise Active Directory and make a simple change on an account that you have on both platforms. In this example I’ve updated the Job Title details on the account Edward Tester.

Then log onto the member server where the dirsync tool is installed.

Navigate to the following directory. C:\Program Files\Windows Azure Active Directory Sync and run DirSyncConfigShell.psc1

Type Start-OnlineCoexistenceSync. Press Enter. This will force a sync between you on-premise Active Directory and Windows Azure Directory Services.
