New Outlook’s Copilot-Driven Summaries

New Outlook is an acceptable email client. Some dislike its lack of support for different features, like COM add-ins. Then Copilot gets involved and adds options to generate morning briefing and nightly wrap-ups without any way to disable the feature for individual users or the entire tenant. Plugging Copilot in like this will please some people, but I suspect that it will harm the reputation of new Outlook, especially without settings to stop Copilot seeking to be quite so helpful.
