OLSync Prerequisites

Topic Last Modified: 2010-02-25

Before you deploy Outlook Live Directory Sync (OLSync), make sure you understand these prerequisites.

The "out-of-the-box" OLSync solution requires Directory Domain Services (AD DS) and Active Directory directory service on-premises. OLSync supports an on-premise topology where only AD DS and Active Directory is deployed or where Microsoft Exchange Server 2003 or later versions of Microsoft Exchange is deployed. Learn more at Implement Outlook Live Directory Sync.

Current version of OLSync set up file

Galsync.msi

Download the Galsync.msi here. The Galsync.msi is on the Microsoft Connect download page. To access and download the Galsync.msi, you must be signed in with the Windows Live account that has access to the Live@edu Microsoft Connect site.

Don't know which Windows Live account has access to the Microsoft Connect download page? If your organization is running Outlook Live, a representative from your organization had to use a Windows Live account to set up the initial Outlook Live domain. That initial Windows Live account is the account that you must use to access the Live@edu Microsoft Connect site.

Internet connectivity

The computer running ILM 2007 FP1 must be able to communicate with both the internal Active Directory servers and Outlook Live.

 

ILM prerequisites

You can't install OLSync on an ILM server that is running other management agents.

If you are running the pre-release version of the Outlook Live Management Agent (OLMA), referred to as R2 ELMA (Release 2 Exchange Labs Management Agent), R3 ELMA, or Exchange Labs Management Agent (ELMA), on the computer running ILM 2007 FP1, see Upgrade ELMA or GALSync 2010 to Outlook Live Directory Sync.

If you are running other management agents on the computer running ILM 2007 FP1, you must either install OLSync on another computer or remove the management agents from the computer running ILM 2007 FP1 before you install OLSync. For information about how to remove existing management agents, see How do I delete CS and MV data, and decommission Management Agents?
