I was the instigator of one of those discussions, from Sept.2003. :-)

I don't know specifically about the Outlook ES, but when I queried
Avocent's technical support that Fall, the answer I got back was,

     "While our switches do support mode 3 keyboard, it is
      currently only in the 101/102 keyboard layout. The
      additional keys would not pass through."

I got similar negative responses from Adder, Linksys and Belkin.
I didn't expect anything different from Belkin, but Adder had a
nice little switch I would've liked to buy...too bad...

The other piece of information I've gleaned from my research is
that essentially all of the switches put the physical keyboard
into mode 2, then translate to/from mode 3 for the VMS connection.

Apparently Raritan does the translation with a per-system-connection
adapter (Alan, correct me if I'm wrong; I don't have any personal
experience with Raritan).

Rose does the translation in the switch if you get a model that
supports this: "ServeView +" / "ServeView Pro" do, as well as
their more expensive UltraView series.

Christoph Gartmann has noted that even with the ServeView, you
may need to (temporarily?) connect a/the keyboard directly to
the Alpha system on reboot to get the full set of keys recognized.
Again, I don't have personal experience with the ServeView...
although I'm trying to find one I like on eBay...

As others have said, all the LK46y-xx keyboards (at least the US
versions) have the same key layout and are all compatible with a
standard PS/2 keyboard connection. IIRC, the LK46W-xx is white.
I have an LK461-A2 (beige) at work and an LK462-A2 (black) at home.
The new LK463-xx has a USB connector, plus a USB-PS/2 adapter, so
it can be used with both Alphas (and older PCs), and with new PCs
and (presumably) Integrity (IA64) servers. The only difference
I've noticed between the various models is that the newer ones feel
cheaper/have poorer action. :-(
