Since it appears Novell isn't going to have a iPhone solution anytime soon,
what third party solutions are out there that will accommodate both
GroupWise and Exchange?

We have kept our options open by using Barracuda for both spam/virus and
message archiving which it will go either way, but what is available that I
can use now with GroupWise and without any license or major server change,
and later down the road go with Exchange?

I have been told last week that we can't keep waiting for a iPhone solution
for GroupWise and must investigate options. So far the majority have gone
with BlackBerrys and love them but a few department heads who make our
departement choices have iPhones so this time it's become serious.
