EWS调用FindItem查询联系人文件夹返回ErrorNonExistentMailbox，但FindFolder正常

我们的应用通过EWS备份Exchange（含Office 365）邮箱，采用OAuth2认证，使用Exchange管理员权限账号，通过Exchange Online Management模块cmdlets获取邮箱列表及对应全权限。应用运行多年正常，但近期调用FindItem查询联系人文件夹时返回ErrorNonExistentMailbox错误，调用FindFolder查询同一文件夹则成功，其他文件夹（如日历、任务等）无异常。

相关请求与响应日志如下：

更新说明：若联系人项位于非联系人文件夹（如已删除邮件），调用GetItem操作也会出现相同错误。
