所以问题在于GMail不会不显示X-ALT-DESC参数的html内容。好奇的是，Hotmail的一切都很好 - 它用X-ALT-DESC中的接受，忽略按钮和格式化的HTML消息显示事件面板。 GMail仅显示事件信息面板。
X-ALT-DESC 是一个MSFT特定扩展名（请参阅 MSND on iCalendar / X-ALT-DESC ）
您可以查看 RFC 到请仔细检查。
考虑到与微软的hotmail关系，他们支持它是很有意义的，并且可能对Google为什么不支持MSFT专有功能有一定的意义。 / p>
We need to inform our customers about upcoming appointments. So I send them iCalendar invites in order to create appointments in their calendars. The example of iCalendar invite can be seen below.

So the problem is that GMail doesn't display html contents of X-ALT-DESC parameter. Curious, that everything's ok with Hotmail - it displays event panel with "Accept", "Ignore" buttons and formatted html message from X-ALT-DESC. GMail displays event info panel only.
The X-ALT-DESC is a MSFT specific extension (see MSND on iCalendar/X-ALT-DESC)
you can check the RFC to double check.
Given hotmail relation to Microsoft, it makes sense for them to support it and probably also some sense as to why Google would not support a MSFT proprietary feature.
