Hey there! Nice to meet you!
Since you have two-factor authentication (2FA) enabled, do you have the 25-character recovery codes for the 2FA?
Important: If you have an active 2FA, the account recovery webform (ACSR) will inform you that your recovery request will be ignored.
If yes, please go to account.microsoft.com > Forgot Password > provide the verification codes if you have access to another verification method besides your recovery phone number > click "I don't have any of these" on your recovery phone number > click "Yes" on the 25 recovery code (if you have one) > from here, you will be asked to wait 30 days in order to update your security info and recover your account.
During this time, you will not be able to sign in to sites or services with your account.
However, if you do not have access to all of your verification methods and the 25-recovery codes from your 2FA, I'm afraid it is no longer possible to recover/verify the account.
Thank you for your understanding.
Best regards,
Darhyl
