Can't find the response group agent that's synced from an existing distribution list in Skype for Business Server 2015

Applies to: Skype for Business Server 2015

Symptoms


In Microsoft Skype for Business Server 2015, you add a user to a distribution list. Then, the response group agents are synced from this distribution list. When the Skype for Business server doesn't find a response group agent, it will create the group agent. However, the server still can't find the agent.

Cause


This issue occurs because the users don't have the msRTCSIP-OriginatorSip populated so that the filter that's used to find the group agent isn't correct.

Resolution


To fix this issue, install the July 2019 cumulative update 6.0.9319.559 for Skype for Business Server 2015, Core Components.
