Is there a road map on full EWS support, or is that not planned at all?

Many third party systems can integrate with Exchange wrt. calendars, but they don't seem to work with Kerio.

One of the things, that's not working correctly, is taht you don't seem to support RequestServerVersion.

When you try to connect to Kerio thinking it's an Exchange 2013 server, the correct answer from an Exchange-server when reporting InvalidServerVersion should be:

<?xml version="1.0" encoding="utf-8"?>
<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body>
<s:Fault>
<faultcode xmlns:a="http://schemas.microsoft.com/exchange/services/2006/types">a:ErrorInvalidServerVersion</faultcode>
<faultstring xml:lang="da-DK">The specified server version is invalid.</faultstring>
<detail>
<e:ResponseCode xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">ErrorInvalidServerVersion</e:ResponseCode>
<e:Message xmlns:e="http://schemas.microsoft.com/exchange/services/2006/errors">The specified server version is invalid.</e:Message>
</detail>
</s:Fault>
</s:Body>
</s:Envelope>


Kerio reports:

<?xml version="1.0" encoding="UTF-8"?>
<Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Body>
<Fault>
<faultcode>Client</faultcode>
<faultstring>Validation constraint violation: invalid value in element 't:RequestServerVersion'</faultstring>
</Fault>
</Body>
</Envelope>

The support of EWS protocol is constantly improving, we are adding new supported clients, but the protocol is not fully covered yet.
The RequestServerVersion response is correct, this field has predefined set of values, any other (newer) version is simply unknown/invalid value. Most clients understands this behavior and falls back to the older version, it shouldn't cause any trouble.
