Microsoft现在支持Java EWS API吗？这个疑问出现是因为我开始在他们的网站上看到“档案画廊已经退役”。

您需要为初学者加载strings.properties文件（应该在下载的API的基目录中）。否则，它就找不到错误消息，并抛出您所看到的异常。有点讽刺的是，它在处理错误时会抛出一个错误。将其放在resources文件夹中（或者您喜欢的任何地方），并将其加载到Strings.java类中。实际上有一堆注释出来的代码就是这样做的。加载它，你至少应该能够得到破坏你的流媒体订阅的实际错误。或者，附加一个跟踪侦听器并打印响应的XML，这样您就可以从中查找错误消息。
啊，你有点改变了。微软已经有一年半没有更新EWS Java 1.2了。项目本身已经移动到一个新的页面，所以它仍然可用:
http://code.msdn.microsoft.com/Exchange-EWS-JAVA-API-12-1A5A1143
他们短暂地使用了Apache2.0许可，但显然这是错误的，他们恢复了旧的许可。我认为微软从来没有“支持”过EWS Java。1.2的许可明确表示它是一个“原样”产品，他们不支持它。
我非常希望MS能够提供一个开放源码许可，或者至少修复一些bug，给它一个适当的存储库，等等。如果有的话，我会有一个充满bug修复的桶来提交。在这种情况发生之前（如果有的话），假设它仍然不受支持。对它的唯一支持是Technet，SO等，还有你自己。
