Can you help me understand please?
I learnt Outlook 2011 for Mac uses EWS protocol for doing emails. How about the Outlook 2010 or 2007 for Windows? Do they use EWS as well?
Also, inside my office my Outlook for Windows connects to Exchange server through the LAN. What protocol does my Outlook use to connect the Exchange for doing emails?
In terms of efficiency, is EWS slower?
