Hi Keegan Crossley, thanks for posting here in Microsoft sorry to hear that, since you've already tried the usual recovery steps and confirmed your account status shows no problems, one alternative is to try signing in via Outlook's desktop app, not the browser or mobile app, which sometimes bypasses web-based lockouts.
Also, check if two-factor authentication (2FA) is enabled and causing a silent block to try disabling it temporarily via recovery options if possible, to do this simply go to https://account.microsoft.com/security then sign in, if possible, using your credentials then under “Advanced security options”, look for Two-step verification, If enabled, click “Turn off” and follow the prompts, Try signing in again after disabling.
I hope this helps you, let me know how it goes.
