I am getting ready to present a hardware/software refresh. We are currently running Exchange 2007 and I would like to move to Exchange 2010. The cost to upgrade our company will be about $7,000 for licensing and CALs.
The archiving looks nice, better OWA for browsers would be nice but isn't a deal killer. We have a trixbox and I know they improved UM but I have never used UM so I don't even know if we would use it. So beyond these and being on the newest version can you guys help me justify.
