We currently have an a 2010 Exchange server running on Server 2008 R2 Standard as a VM. We had a third party vendor come in and set this up for us due to other projects we were doing at the time.
This VM has 64G of RAM, but we have been told that since R2 Standard was used, we are limited to 32G. We have had small issues with this Exchange since day one, and have had to correct many things that the vendor left out or configured incorrectly. There is another software package on there that Archives our email and is used to prevent SPAM, and that doesn't work as it should all the time either.
The question is what problems should I be aware of when installing a whole new R2 Enterprise Server with Exchange 2010 on the same domain, and trying to migrate everything from one to the other? It sounds easier than I know it is going to be, so I was coming here for advice.
I'm getting some heat on this one since one day internal emails wont work, the next people can send to external emails but can't receive, and the following it is exactly the opposite. I can work through Exchange once it is up, but setting up and implementing is something that I have limited experience with.
