Compatibility

I've been trying to install Exchange Server 2007 on Server 2008 R2 and running into trouble. Little did I know that until SP3 of Exchange 2007 it wasn't a supported option! Check this out!

After days of trying to install, my installs finally went through after leaving the machines up and running for a day. Perhaps they needed to successfully replicate.
