using EWS differences beetwen with Exchange 2010 server and Exchange 2007 server

Question

I 'm using EWS to cominicate with Exchange Servers both 2010 and 2007... There is a versionning property for ExchangeServerBinding object. I googled but found out any critical differences while EWS working with Exchange2010 and Exchange2007..

So is there any differences while accessing Exchange2010 and Exchange2007 with EWS?

Answer 1

If you talk to exchange 2010 with 2007's wsdl - no differences at all.

If you talk to exchange 2007 with 2010's wsdl it works pretty fine as well, however you should be careful not to use 2010 specific methods/properties. EWS 2010 introduces new functionality like associated items you can't use from 2007
