Outlook Windows客户端OnNewMessageCompose等事件无法触发求助

问题概述 #

• 我们的Outlook插件已注册OnNewMessageCompose和OnMessageRecipientsChanged事件，在浏览器版（outlook.office.com）正常运行，但在**Windows客户端Outlook 365（版本2209 内部版本16.0.15629.20068 32位）**中完全失效
• 此前功能正常，近期在Current Channel (Preview)频道失效；切换至非预览频道曾暂时解决，但目前两个频道均无法运行
• 特殊症状：开启调试时事件可触发，关闭调试则失效，且撰写窗口顶部提示：We're sorry, we couldn't access <app-name>. Make sure you have a network connection. If the problem continues, please try again later. Dismiss

事件处理函数（简化版） #

function EventOnCompose(event) {
    HandleComposeEvent(event, false)
        .then((result) => console.log(result))
        .catch((err) => {
            console.error(err);
        })
        .finally(() => {
            console.info("Event completed");
            event.completed();
        });
}

function EventOnRecipientsChanged(event) {
    HandleRecipientsChangedEvent(event, false)
        .then((result) => console.log(result))
        .catch((err) => {
            console.error(err);
        })
        .finally(() => {
            console.info("Event completed");
            event.completed();
        });
}

事件关联代码（addinfunction.js末尾） #

Office.actions.associate("EventOnCompose", EventOnCompose);
Office.actions.associate("EventOnRecipientsChanged", EventOnRecipientsChanged);

已尝试的排查步骤 #

• 官方自动启动事件调试方法无效（因事件根本未触发）
