Removing ‘disable plain auth property’ it causes error saying ‘Failed to validate account: Failed to connect the email server: outlook.office365.com Cause: AUTHENTICATE failed. (Reason: AUTHENTICATE failed.; Resolution: Please check for valid properties.)’

Authentication failure suggests invalid credentials (email id or password). I assume you have verified these. You mention that you are able to login to this account. Is multi-factor authentication setup for this account? That might cause problems too. Adding the debug property may help.
