Office.Conext.mailbox.displayNewMessageForm在移动设备中不工作

我试图在Outlook Web Add-in中单击按钮来创建新的邮件表单，但我使用了displayNewMessageForm。该功能在Web浏览器和Outlook桌面上运行良好。但同样的功能在Outlook Mobile中不起作用。

你们的Outlook手机有这个功能吗？

更新：如果您只想在移动设备上使用它，请使用以下代码

Office.context.ui.displayDialogAsync(url,
    { height: 75, width: 80, requireHTTPS: true });

其中URL变量可以是这样的

var url = "mailto:someone@example.com?Subject=Hello%20again";

解决方案

displayNewAppointmentForm(在标题中)和displayNewMessageForm(在问题中)是两个不同的功能。Outlook for iOS或Outlook for Android不支持displayNewAppointmentForm函数。同时，当您在清单文件中正确指定对移动设备的支持时，displayNewMessageForm函数将在移动设备上工作。有关详细信息，请阅读Add support for add-in commands for Outlook Mobile文章。
