I have been reading up on Exchange 2010 and the new Exchange Web Services, but there seems to be a lot of confusion.
According to Wiki (http://en.wikipedia.org/wiki/Microsoft_Exchange_Server
"Exchange Web Services (EWS), an alternative to the MAPI protocol, is a documented SOAP based protocol introduced with Exchange Server 2007 which significantly reduces synchronization time between the server vs. WebDAV, which is used by Exchange Server 2003"
On one hand it is saying that EWS is the replacement to MAPI, on the other it is implying that EWS is the successor to WebDav.
Can anyone expand? What is the primary point of EWS -
a) As some sort of long term replacement to MAPI?
b) A replacement for WebDav
c) A method for non-MS products to connect to Exchange mailboxes
Would be grateful if someone could clear this up! If, indeed, it is a long term replacement for MAPI, does that indicate that MS will move Outlook (fat client) away from MAPI and towards EWS in the future?
