To keep your on-premises user directory synchronized with your Microsoft Office 365 directory, you may need to use a different tool than you used with Microsoft Live@edu. In most cases, you will need to use the Windows Azure Directory Sync tool.
Typically, if your existing directory synchronization solution isn’t customized, there is no end-user impact when changing to the Directory Sync tool. If your existing solution is customized, follow the directions for updating your synchronization solution below to minimize potential end-user impact. Note that you can’t provision users during the initial synchronization using the Directory Sync tool.
Before starting, learn about directory synchronization so that you understand the terminology, system requirements, and how it works.
Outlook Live Directory Synchronization (OLSync)
Outlook Live Management Agent (OLMA), Active Directory, and custom code
Custom Windows PowerShell cmdlets and Active Directory
Hotmail Management Agent (MAv3)
OLMA, no Active Directory, and custom code
To switch from OLSync to the Directory Sync tool, complete the following steps.
You can continue to use custom Windows PowerShell scripts, but will need to update them after the upgrade based on changes to Exchange Online cmdlets. For more information, see Windows PowerShell.
If you want to move to the Directory Sync tool, complete the following steps.
Depending on where you are located, support for MAv3 with Live@edu ended on April 20, 2013 or will end on May 27, 2013. MAv3 is not supported in Office 365 and will stop working once the upgrade to Office 365 starts, even if the upgrade is initiated before May 27, 2013.
To switch from MAv3 to Directory Synchronization, complete the following steps.
Microsoft fully supports Active Directory synchronization in Office 365, Due to the custom nature of non-Active Directory implementations of directory synchronization, Microsoft cannot provide detailed change instructions for Office 365. You are responsible for the update of your on-premises directory synchronization to Office 365.
In order to give you time to update your current solution for directory synchronization, you can continue to use the Outlook Live Management Agent (OLMA) for 30 days after you upgrade.
