我们有一个 TFS 2012 服务器并尝试启用电子邮件警报。但是，我们从未收到它们。

我已经设置了团队警报和特定于我的帐户的警报。在 TFS 管理控制台中配置 SMTP 设置时，我尝试将凭据留空，并使用我自己的凭据。两者都不起作用。

我还在 C# 中创建了一个简单的控制台应用程序，使用System.Net.Mail.SmtpClient该类来测试来自 TFS 服务器的带有和不带有我的凭据的电子邮件，并且它可以工作。

事件日志不显示任何相关的错误消息。

如何解决和解决此问题？

使用本文中的信息，我能够从数据库作业历史表中提取以下错误消息。

elapsed time: 00:00:00.5255295, sql calls: 35, sql connect time: 00:00:00, sql execute time: 00:00:00.0311960, non-sql time: 00:00:00.4943335 (94%), cpu time: 00:00:00.0312002 ( 5.9%), avg connect time: 0.00 ms, avg execute time:  0.9 ms. All methods quick. All sql calls quick. CollectionError: CreateEvent != TransformEvents. CollectionError: AfterReadSubscription != ExpandEvents.

There were errors or warnings during notification delivery.

0/0 emails delivered.
0/0 soap notifications delivered. 
1 errors.

-------------------------------
Notification not delivered due to error during filtering of restricted content.

Notification: WorkItemChangedEvent (DeliveryType: EmailHtml; Address: )

Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

如此处所述，我检查了安全设置->本地策略->安全选项->“系统加密：使用符合 FIPS 的加密、散列和签名算法”值的本地安全策略，并且它已经设置为禁用。

重新启动Visual Studio Team Foundation 后台作业代理服务为我修复了这个特定错误。
