After upgrading my AD/DC from 2003 to 2012 R2, will my exchange 2007 and outlook 2007 clients still work

I am upgrading my Domain Controllers to 2012 R2 in a couple of days.

My concern is whether I need to prep my Exchange environment in any way before the domain controller upgrade to ensure we are still able to send and receive e-mails even after the upgrade.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes, that is supported. But you cannot raise your forest functional level up to 2012 R2.

Yes they are all supported as long as you do not raise the forest to Windows 2012 native. Also make sure all your clients are Windows 7 and above as Windows xp doesn't work with 2012 domain controllers.
