I get all the way through step 18, when after logging into my Microsoft Account using the stored credentials, I get a prompt to allow the application access, but then I am presented with the OAuth Redirect URL to login. Below is a screenshot.
From what I can tell from the attached video, I shouldn’t be seeing this message.
At a guess you are n8n desktop, The desktop app automatically logs you in but when you do the redirect for oauth you will be prompted for credentials that are generated on install. You can find the credentials for you install by following the link below.
