Copilot Chat + Outlook: Email Summary Behavior

Sharing my discoveries. 

Copilot Chat is available to Microsoft 365 work or school accounts.

Using Summarize this email in Outlook saves each summary as a Copilot Chat conversation, which can clutter Chat History. There’s no bulk delete; chats must be removed one at a time. This is expected behavior.

Using Temporary Chat for one-time summaries helps keep Chat History clean.
