Question

我们的生产客户正在努力应对以下错误： Office JS API不返回用户标识令牌，这会阻止我们的加载项的全部使用。

我们在日志中看到的错误：

{
    "name": "AccessRestricted",
    "message": "Internal protocol error: '-2147467259'.",
    "code": 9017
}

有时，当笔记本电脑在睡眠模式后醒来时有时会出现，有时则没有。

此外，当我们的代码执行获取用户身份令牌异步时，Office JS API中有时会出现以下错误（但不是每次出现AccessRestricted错误时）：

"Unable to get property 'Execute' of undefined or null reference",
"number": -2146823281,
"stack": 
    "TypeError: Unable to get property 'Execute' of undefined or null reference
     at n.prototype.execute (https://appsforoffice.microsoft.com/lib/1... (truncated by our logging system)

Outlook版本为16.0.8528.2147，并且加载项已固定。附： Office JS API已初始化，这不是此问题的根本原因。

以下是代码：

sfMailApp.OfficeManager.prototype.getCallbackTokenAsync = function () {
    var item = this.getItem();

    return !item.isFake ? this._loadItemAsync(Office.context.mailbox, 'getCallbackTokenAsync') : sfMailApp.utils.resolveDeferred('');
};

sfMailApp.OfficeManager.prototype.getIdentityTokenAsync = function (force) {
    var ls = getLocalStorage();
    var lastUpdateIdentityTokenTimestamp = ls.getItem('identityTokenUpdate');
    var cachedIdentityToken = ls.getItem('identityToken');

    var lastUpdateIdentityTokenDifference = !sfMailApp.utils.isNullOrEmpty(lastUpdateIdentityTokenTimestamp) ? (new Date().getTime() - parseInt(lastUpdateIdentityTokenTimestamp)) : null;

    if (sfMailApp.utils.isNullOrEmpty(cachedIdentityToken) || cachedIdentityToken === 'null' || sfMailApp.utils.isNullOrEmpty(lastUpdateIdentityTokenDifference) || force ||
        (lastUpdateIdentityTokenDifference / (1000 * 60)) > sfMailApp.settings.identityTokenUpdateIntervalMinutes) {
        var deferred = $.Deferred();

        var item = this.getItem();

        if (!item.isFake) {
            sfMailApp.analytics.trackEvent('LoadUserIdentityTokenAsync', 'Start', {
                user: sfMailApp.mailService.userEmail
            });

            this._loadItemAsync(Office.context.mailbox, 'getUserIdentityTokenAsync').done(function (token) {
                ls.setItem('identityTokenUpdate', new Date().getTime());
                ls.setItem('identityToken', token);
                sfMailApp.sessionManager.setIdentityToken(token);
                deferred.resolve(token);
            }).fail(function (err) {
