最近工作中遇到一个问题，本来很简单的一个问题，困扰了我2周
具体：java发送会议邮件到exchange服务器
奇怪：系统有80多家客户，基本大半都有会议邮件的发送，不管是outlook，网易闪电邮，Foxmail另外wps邮箱都可以接收到会以邮件
只有exchange不能接收到会议邮件，收到的只是
BEGIN:VCALENDAR PRODID:-//Events Calendar//iCal4j 1.0//EN CALSCALE:GREGORIAN VERSION:2.0 METHOD:REQUEST BEGIN:VEVENT DTSTAMP:20160805T115502Z DTSTART:20160808T160000 DTEND:20160808T223000 SUMMARY:test LOCATION:test UID:3f3acf56-0b54-4963-bba2-f02d2c222a8c ORGANIZER:1 SEQUENCE:0 ATTENDEE;ROLE=OPT-PARTICIPANT;CN=Developer1:mailto:[email protected] BEGIN:VALARM TRIGGER:-PT10M REPEAT:1 DURATION:PT10M SUMMARY:Event Alarm ACTION:DISPLAY DESCRIPTION:Progress Meeting at 9:30am END:VALARM END:VEVENT END:VCALENDAR
并且邮件中的正文，已附件的形式存在，并且看了网上很多类似的解决方式，综合起来的代码

BodyPart对象不管怎么转码都不能解决问题，并且exchange的服务器设置也没有什么特殊的地方，也没有过滤什么东西，这是为什么呢？
网上找了两种方法：用ical4j和不用
我这里用的就是ical4j，但是不行，不知道其他人是怎么做的
然后我就尝试不用ical4j

}
}

} catch (Exception ex) {
ex.printStackTrace();

}
这样做了，竟然就可以接收到了，我很无语
仔细看代码，没有ical4j的日历对象，也没有把邮件的正文或者日历对象转成 text/html;charset=UTF-8
为什么就可以了呢，很不解，并且这样的写法，其他的邮件服务器也是可以用的
