Hi Patrick! Not yet but I believe the product team is working on supporting this now that Exchange 20101 is complete or it might show up in a later update to the product.
What about timeline? I have a customer that will start using Exchange 2010 very soon and we want deploying FIM 2010 over this platform, so that will mean using FIM 2010 RC1 with Exchange 2007 and then FIM 2010 RTM with Exchange 2010? I have to confirm if the release version of FIM 2010 will be available for Exchange 2010?
