I just notice that talking to Office365 Exchange Web Services at https://outlook.office365.com/ews/exchange.asmx I get this in my SOAP response header:
<Envelope>
<Header>
<ServerVersionInfo MajorVersion="15" MinorVersion="0" MajorBuildNumber="1049" MinorBuildNumber="23" Version="V2_22"/>
</Header>
This means that the Version 'schema version' property now breaks the pattern of versions that we had earlier:
Exchange2007, Exchange2007_SP1, Exchange2010, Exchange2010_SP1, Exchange2010_SP2, Exchange2013
In the schema files I found through Google (searching for <xs:simpleType name="ExchangeVersionType">) I could not find anything later than
<xs:enumeration value="Exchange2013"/> (e.g. at http://msdn.microsoft.com/en-us/library/ee237685%28v=exchg.80%29.aspx)
If I do a SOAP request with this "V2_22" string, I still get valid answers.
<soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:typ="http://schemas.microsoft.com/exchange/services/2006/types"
xmlns:mes="http://schemas.microsoft.com/exchange/services/2006/messages">
<soapenv:Header>
<typ:RequestServerVersion Version="V2_22"/>
</soapenv:Header>
But it now looks as if the returned Version is no longer a reliable way to determine the Exchange server version. If V2_22 is not documented anywhere, who says it will not suddenly change to V2_23 tomorrow?
Question: Does this mean I will now have to change my version detection code to look at MajorVersion and then maintain a cross reference between MajorVersion and ExchangeVersionType myself? That is horrible: another dependency to maintain is another potential code break.
[Edited to add]
This is the actual call that gives the result mentioned in the first paragraph, including the HTTP exchange:
