Teams 日历请求导致 Exchange Server 2016 记录未处理的异常 (maxQueryStringLength)

Question

我们的本地 Exchange Server 2016 正在记录未处理的异常 – 似乎是 Teams 通过 REST 查询日历数据API。

在事件日志中：（example.com 是我们的本地 Exchange 服务器）

Exception information: 
    Exception type: HttpException 
    Exception message: The length of the query string for this request exceeds the configured maxQueryStringLength value.
   at System.Web.HttpRequest.ValidateInputIfRequiredByConfig()
   at System.Web.HttpApplication.PipelineStepManager.ValidateHelper(HttpContext context)

Answer 1

编辑："C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\rest\web.config"

添加

maxQueryStringLength="10240"

至

< httpRuntime />

例如 < httpRuntime maxRequestLength="2097151" maxUrlLength="2048" maxQueryStringLength="10240" requestPathInvalidCharacters="<,>,*,%,\,?" requestValidationMode="2.0" />

我的大小可能超出一英里（最大字符串约为 1956 字节），但这让我无休止地烦恼。

Answer 2

更新 web.config 文件中的 maxQueryStringLength。
