在本月的补丁星期二活动中，在面向Windows 10系统发布累积更新的同时也向Office 365客户端发布了更新，但两个更新都因为错误而被紧急撤回。昨日微软宣布撤回Windows 10 Autopilot更新“KB4532441”之后，今天微软再次宣布由于存在下载错误撤回了Office 365的更新。
在12月11日的更新公告中，微软解释道Office 365 ProPlus用户尝试通过Configuration Manager下载Office 365客户端更新的时候，可能会出现阻止完成更新的情况。目前官方并没有提供导致出现这个下载错误的详细信息。
微软表示在下载本月更新的时候，可能会出现下面三个错误提示之一，包括
• 错误：无法下载内容ID
• 错误：无效的证书签名
• 错误0x800b0004：TRUST_E_SUBJECT_NOT_TRUSTED该对象不受指定操作的信任
根据官方链接的技术支持文档，自Verison 1902（Build 11329.x）及更高版本任意通道在安装Office 365客户端更新之后都会出现上述错误之一。而Verison 1902此前旧版本不受影响。
