Our Spark environment has been in place for quite a few years and consists of around 100 people who communicate using it on a daily basis. Today, an issue I’ve never seen occurred.
One user can see everyone in his group…everyone in his group can see him. When he send a message to anyone, the message appears in their window. But when anyone sends a message to him, a chat window opens but the message is blank.
Does anyone have any thoughts as to what might be causing this?
