I've found putting people in the same room often helps. Especially when there has been an issue. Generally, just actual discussion and a firm reminder that we're all professional adults on the same team is often enough. Recent pandemic events notwithstanding... I'm also a bit gun shy about firing the "problem individual" since I've generally found that particular individual is often the one caught replying and not the instigator. YMMV. Nuance and context and all that. The "heads should roll" thing works but make sure its well targeted and for accurate cause.
