Using New Outlook on Windows for personal email, calendar, and contact management
Your steps are:
- Settings, Apps.
- Delete the new Outlook. (Outlook new)
- Go to the Microsoft Store, search for Mail and Calendar, Install
This is the link to the Mail and Calendar app at the store:

However, the Mail and Calendar app in the Microsoft Store is not Classic Outlook. The OP wants Classic Outlook.
Are you saying that once you delete New Outlook and install the Mail and Calendar app from the store that Classic Outlook returns?
