Setting up multiple staff email addresses

[Debs]

What's the easiest way to set up multiple (50-60) individual staff email addresses, so I can get improved staff communication and cut out wasted paper? Plus I want wifi access in the building.
We have BT business broadband phone system, but the BT support for this doesn't seem able to advise us about sorting wifi or these email addresses. With my domestic broadband package it's already all there!
Any pointers, please.

With BT Business broadband you get 10 email addresses - any more and you need to pay extra.  It can be seen from you online account.

However, for 50 to 60 staff you really should be looking at your own domain and mail server and managing it all yourself.   That way email between staff are sent/received locally rather than sent via teh BT mail network if you tried to use that.
