your library for EWS supports a typed mail message, but no typed contact item, task and appointment (calender item). I read your recommendation in your docs to parse the XML of my own.
Please, when you find time, support this in the future so we must not read and parse xml data.
That's no problem generally speaking but very ugly as a end user.
Your EWS library is very fast and easy to set up, so i prefer it to the original Microsoft's .NET library.
But without the other types it seems to be very unfinished.
