I wear a lot of hats...

"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.

As we don't know your entire topology, we are only going to be able to make general suggestions.

We don't know what network equipment you have in place, connections to your branch offices, etc.

For your setup a good starting place would be.

1.  2 CAS machines
2.  1 MBX server
3.  Exchange Online Protection
4.  Any good backup software...Symantec should be fine.

As for the optimum....that is going to have to be your decision because we simply cannot know your entire environment from a 4 line question.
