Can you help me understand please?<br />
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?<br />
<br />
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? <br />
<br />
In terms of efficiency, is EWS slower?
