Not without having either Exchange 2007, Exchange 2010, or Exchange 2013 AD schema updates applied.
From: [email protected] [mailto:[email protected]] On Behalf Of John Matteson Sent: Friday, September 27, 2013 10:13 AM To: [email protected] Subject: [Exchange] AutoDiscover SCP in AD 2003 Have a question for the Exchange/AD big brains. I have a forest that is a straight Exchange 2003/AD 2003. The schema has not yet been extended for Exchange 2007 or beyond. We are looking to migrate all users off this Exchange service into an existing Exchange 2010 environment that's running under AD 2003, but extended for Exchange 2010 (obviously). In a previous migration, we ran an export cmdlet to install a SCP into another AD forest for Exchange 2007, so that network users could use autodiscover to build their new profiles once migrated. The mailboxes are being migrated, but the users are continuing to use their original credentials to access resources in the original domain. They are getting new credentials for mail. My question is this, can the AD 2003 running Exchange 2003 support a SCP for Autodiscover from a trusted domain? Any information or pointers would be of great assistance. John M.
