After notifying customers and partners that Exchange Server 2007 wouldn't be able to run on Windows Server 2008 R2, the latest version of WIndows Server, the Exchange team has reversed its decision.
In a posting on the Exchange Team Blog, Microsoft officials said they'd heard the negative feedback loud and clear. Customers didn't want to be forced to move to Exchange 2010 before they were ready, just so as to be able to run a version of Exchange on Windows Server 2008 R2.
To fix the problem, Microsoft is prepping an update that will be out some time next year. From a November 4 blog posting by Kevin Allison, General Manager of Exchange Customer Experience:
"In the coming calendar year we will issue an update for Exchange 2007 enabling full support of Windows Server 2008 R2. We heard from many customers that this was important for streamlining their operations and reducing administrative challenges, so we have changed course and will add R2 support. We are still working through the specifics and will let you know once we have more to share on the timing of this update."
One Exchange 2010 caveat that seemingly hasn't changed: Users who want to run Exchange 2007 and Exchange 2010 together must upgrade to Exchange 2007 Service Pack (SP) 2.
Microsoft is slated to provide customers with Exchange 2010 final bits starting the week of November 9. Microsoft released to manufacturing Exchange 2010 in early October.
