Does it do it?

Like on the Blackberry?

Is it operator dependant?

i guess it is not , as it have windows mobile operating system

I have no clue what wael means above, but there's no built-in push email support in the N95 (push email has no Windows Mobile OS dependencies, and the N95 doesn't run Windows Mobile).

I don't know for sure if the sw here (Blackberry Connect, Mail for Exchange, etc.) works on the N95:

There supposedly is support for Push email. A vodafone leaflet i got with the phone tells me that it does support it. Havnt tried getting it working though.

The only push mail I have got working so far on the N95 is Roadsync by Dataviz and this syncs ok with any Exchange 2003 + server.

Free trial is available.
Havent had a chance to really test what it does to the battery life.
Its likely that Emoze wil also support the N95 soon,
