With the retirement of the traditional Microsoft Exchange Web Services protocols by Microsoft in favor of the newer Graph Api protocol only, Apple Mail can no longer access Outlook and Exchange based accounts.
Until Apple updates the Mail app to support the newer Graph Api, there's unfortunately not much that can be done.
You can download the newer Outlook for Mac app from the App Store and use that to access Exchange email accounts while we wait for Apple to implement Graph API into the Mail app.
