"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.

The exchange update to SP3 will only work if all the MS updates have been done. Also it's best to do a full backup of exchange before the update. I normally run Best Practices as well and clear any outstanding items.

Thank you. Just to be clear. Thats all the updates on the Exchange server, correct?

Exchange 2010 SP3 will work on a 2008 (assume you mean R2?) SP1 server and is fine in a 2012 AD domain.

You do not need to install all exchange updates before SP3 as it is cumulative so you can go directly to SP3 then install CU10

I don't think I am being clear. The Exchange server is on 2008R2 but we upgraded the domain controller to 2012.   I am wondering if that can cause an issue being that I don't have a 2008 level DC  but am running 2012 level AD.

as i said, it works fine in a 2012 AD environment...
