Designed to replace the current Mail and Calendar apps, the new Outlook can only be removed after it's been installed.

Microsoft announced last year that it would be retiring the Windows Mail & Calendar apps in favor of the new Outlook at the end of 2024. As of January 1, these apps are no longer functional and will refuse to send or receive any more emails.
