Nokia now supports some N-series devices, but they seem intent in perpetuating their belief that only corporate customers use Exchange (get with the program, guys, some of the largest ISPs in Portugal give away ActiveSync service to consumers).
Update 1: Well, directory lookup works for me on an (officially) unsupported S60 3rd Edition device, but Mfe itself does not and fails with an “unsupported device” error – which is odd, considering that 1.3.1 worked OK for me.
I suppose that I might be able to somehow keep the directory lookup application and revert to 1.3.1 if I hack the right bits, but I find Nokia’s position on this to be absurdly irritating – what is the point of their having a single OS when they persist in locking applications to specific device models?
Update 2: The E90 works great (directory lookups, multiple recipients, meeting request processing, etc.), although it is still apparently impossible to originate meeting requests from the client.
