What happens when I convert a lead to an opportunity using a smart action?

You can take actions on lead items from your list item by using the Actions menu (three dots on the right of the item) on the My List of Leads page.

For example, you can use the Convert quick action to covert a lead to an opportunity. In the Convert Lead window, you can change the opportunity name, enter an account and contact, and reassign opportunity ownership. When you click Submit, the application creates the new opportunity and you can view it from the Opportunities UI.

The conversion process copies key information from the lead into the opportunity and links the converted lead to the new opportunity. Copied information includes notes, interactions, and conversation messages from the lead activity stream.
