Consider the following scenario:
- You are a developer in a Microsoft Skype for Business Server 2015 environment.
- You use Persistent Chat Software Development Kit (SDK) to manage user roles in a chat room by invoking BeginAddUsersOrGroupsToRole method.
In this scenario, the method call may fail, and you receive the following error message:
NodeSetting.ONLINE_USER_COUNT_SETTING is immutable
This issue occurs because room search command tries to set a parameter value that's an external read-only field.
