WCF failures occur when Dynamics 365 clients communicate through a Load Balancer

View products that this article applies to.

Symptoms

When Dynamics 365 web servers are configured behind a load balancer, exceptions may occur from WCF-based clients such as the Outlook Client, Email Router, or SDK applications when communicating over web services. Examples of these exceptions may include:

"An unsecured or incorrectly secured fault was received from the other party"

"SecurityContextException"

Cause

The issue occurs due to missing or incorrectly configured persistence settings on the load balancer, which can cause WCF failures when the web server attempts to read a token that was issued by a different web server.

Resolution

Dynamics 365 requires IP based persistence to be configured on the load balancer.
