With that large of a setup I honestly think you ought to not look at Ubuntu and instead look at Red Hat or SuSE. Ubuntu has good community support and offers some commercial support, but they are on another planet compared to Red Hat and SuSE. For the x86 world, Red Hat is probably the best supported, and Red Hat has the largest network of support engineers and cooperating vendors.
For example, Red Hat is soon about to fully support Exchange 2007. Fedora 10 is featuring Samba 4 and _native_ Exchange 2007 MAPI support. _Native_, no OWA hacks or other such, so Evolution will work out of the box. If you're in an Exchange 2007 environment this will make a migration much easier for you, as you can deploy the workstations while keeping your mailserver, doing that final migration last.
In all fairness, Redhat hasn't announced RHEL6 yet. RHEL 5.3 was just announced however, but that isn't going to be based of Fedora 10+
