Exchange Server and its relationship to Active Directory

Updated on 25.03.2013


This article should give an overview about the relationships with the different Exchange Server versions and the requirements for Windows server 2008/2008R2 and Windows Server 2012 Domain controllers. Even if some are NOT supported i will list them here as they should work.


Within the last years we’ve got several new Windows Server versions, 2008 and 2008 R2 and now Windows Server 2012, and also some new Exchange Server versions, 2007, 2010 and now 2013. They now maybe have to coexist even with Windows server 2003/2008/2008R2 and Exchange Server 2003/2007/2010 or should be upgraded to new versions.



Exchange Server 2000 and Windows Server 2008 Operating System/Domain Controllers


- Exchange 2000 can’t be installed on Windows Server 2008.


- Exchange 2000 SP3 isn’t supported when working together with Windows Server 2008 or higher DCs.


- for upgrading to Windows Server 2008 or higher you have to check that no Exchange Mangled Attributes exist, this applies also for Windows Server 2008.


- if there is no other option then it should be possible to use the Windows Server 2008 DCs in a different site then the Exchange 2000 SP3.     !!!Keep in mind this isn’t supported configuration!!!


- if you really must use both in the same site then some additional configuration should help to hardcode (default is automatic discovery) the DSAccess on the Exchange 2000 to DCs with Windows Server 2003 or Windows 2000 Server OS. Open ESM and choose the “Directory Access” tab of the Exchange server properties. See also Directory server detection and DSAccess usage and Revert DSAccess to default for details.     !!!Keep in mind this isn’t supported configuration!!!

- in place upgrades to Exchange 2007 or higher aren’t possible, the needed process is Exchange Organization transitioning.


- the Planning Roadmap for Upgrade and Coexistence with Exchange 2010 from Exchange 2003 and Exchange 2007 contains all needed information.

Upgrading Active Directory to Windows server 2008, when Exchange server 2000 or Exchange server 2003 is installed

For more detailed information also about Exchange 2007 and Exchange 2010 see “Exchange Server and it’s relationship to Active Directory


To upgrade an Active directory forest/domain to a newer OS version you have to check some prerequisites.


If Exchange 2000 is running in the existing Windows domain, then first check with the following article that no mangled attributes exist, applies also to Windows Server 2008. http://support.microsoft.com/?id=314649


If Exchange 2000 Service pack 3 is installed, it can be used in an Active Directory Forest that contains Windows Server 2008 DCs but the Windows server 2008 DCs shouldn’t be in the same site as the Exchange 2000 server. If Windows Server 2008 DCs MUST run in an AD site that has Exchange 2000 servers, you have to configure the Directory Service Access (DSAccess) on the Exchange 2000 Server servers in the site, to use a DC that is running either Windows server 2003 or Windows server 2000. Configuring DSAccess manual will NOT provide any fallback to another Domain controller or Global catalog server. http://support.microsoft.com/kb/250570


UPDATE: Exchange 2000 isn’t supported to be used with Windows server 2008 DCs according to the “Exchange Server Supportability Matrix” but should work according to the article from the Exchange specialists “Exchange Server and Windows Server 2008“.


If Exchange 2003 is used, make sure that Exchange 2003 Service pack 2 is installed.


RODCs can be used without any problem in the forest but each Exchange server version requires a writeable Domain controller and a writeable Global catalog server.


UPDATE: According to the “Exchange Server Supportability Matrix” it is also supported to use Windows server 2008 R2 Dcs, when Exchange 2003 SP2 is installed.
