How to detect exchange server version using EWS API?

Question

Hello there,
I am new to this EWS area and I am looking for a way to detect exchange server version information whether user mailbox is exchange 2007 or 2010 or 2013 etc. Apologize if we already have such question posted earlier, I am posting it here as I could now find
any such forum.
1. Is it possible to fetch this information using EWS API? I am using EWS 2.0 libraries for now.
2. If yes, how can i get that information? can you please provide some sample?
Thanks in advance.

1. On 2010 and above you can use Autodiscover to get the EWS Schema version this is most accurate method to use. It's import to understand the EWS Schema version vs just the Server there is a good write up in
http://msdn.microsoft.com/en-us/library/office/dn741586%28v=exchg.150%29.aspx . Some EWS Managed API code to get the server version would look like
AutodiscoverService adAutoDiscoverService = new AutodiscoverService();
adAutoDiscoverService.Credentials = ncCred;
adAutoDiscoverService.EnableScpLookup = true;
adAutoDiscoverService.RedirectionUrlValidationCallback = adAutoDiscoCallBack;
adAutoDiscoverService.PreAuthenticate = true;
adAutoDiscoverService.TraceEnabled = true;
adAutoDiscoverService.KeepAlive = false;
GetUserSettingsResponse adResponse = adAutoDiscoverService.GetUserSettings("[email protected]", (new UserSettingName[1] { UserSettingName.EwsSupportedSchemas }));
This won't work on 2007 but the other method you can use is if you set the version to 2007_SP1 and make a call like binding to the Inbox folder and then check the result in ServerInfo http://msdn.microsoft.com/en-us/library/microsoft.exchange.webservices.data.exchangeservicebase.serverinfo(v=exchg.80).aspx
. (Note if your are going to use ServerInfo you do need to make a request like a FolderBind ).
