Managing personal Outlook.com account settings, security, and privacy
Hi Blaze3609! This is Raech. I'm an Outlook.com user like you and I'm happy to help.
This could be a browser issue. First, try signing up for an account via Incognito or InPrivate browsing. If the problem persists, try clearing your cache and browsing history also. You can also try other browsers.
I'll be here in case you need any further help.
