Dear Sam Bryl,
Good day! Thank you for posting to Microsoft Community.
I'm sorry to hear that you're experiencing issues with the editor in the New Outlook for Windows. However, in order to understand the problem and provide possible solution, May I please double confirm if you're using a Microsoft 365 business email account, a Microsoft personal account (such as outlook.com, hotmail.com, or live.com), or a third-party email provider account such as Google workspace?
- Are you using Exchange, IMAP or POP3 email set up?
- May I please double confirm if the Microsoft editor is grayed out (not active) or Microsoft Editor is active but not working properly?
- May I please double confirm if you have tried to enable "Privacy Settings" option in the new outlook? If not, please kindly navigate to Settings > General > Privacy and Data > Privacy Settings > enable the toggle "Turn on optional connected experiences", then check if there is any difference.

I look forward to your response. Kindly note that the above requested information is required for further analysis and troubleshooting of your situation. Your patience and cooperation are much appreciated.
Thank you for your precious time. Have a nice day.
Sincerely,
Libeamlak | Microsoft Community Moderator
