C#调用ExchangeService.AutodiscoverUrl报E_INVALIDARG错误求助

问题详情 #

• 一段稳定运行7年的C#代码，调用exchangeService.AutodiscoverUrl("有效邮箱地址")时突然失效，目标邮箱仍正常存在于SBS 2010服务器上
• 抛出错误：The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
• 已确认邮箱地址有效、密码未修改（若密码错误会触发其他类型异常），但Windows返回的异常无有效诊断信息

已尝试的无效解决方案 #

• 清理缓存：服务器上不存在方案提及的缓存目录
• 微软问答页面的第一个修复方案：执行后问题未解决，控制台也未输出任何报错信息

堆栈跟踪 #
