Event ID 56417 when QoE reports have ApplicationSharingType and OS values longer than max length limit

Symptoms
Consider the following scenario:
  • You have deployed the Quality of Experience (QoE) service in a Microsoft Skype for Business Server 2015 environment.
  • A user shares several applications in a single Application Sharing session. For example, a user selects Present Programs multiple times to share multiple email messages in the same session.
In this situation, the titles of the shared email messages are concatenated and sent in the QoE Report to be logged in the Skype for Business QoEMetrics database.

If the titles add up to longer than 256 characters, the session cannot be logged in the Skype for Business QoEMetrics database and the following event is logged in the Skype for Business Server log on the front end server:
