- This is almost always due to your IP being blocked at Outlook/Hotmail. Outlook/Hotmail are very strict with blocking IP's. 

An IP can usually only make 2-3 accounts before being banned for the day. If you are looking to make bulk Outlook accounts you'll need private proxies. VPN's will usually not work as well since those are shared IP's and many have already been banned. We highly recommend using our free pre-created emails instead of trying to create your own. 

- Sometimes this is because captchas are being solved incorrectly or your captcha balance is empty.

If you find that these are not the reason you can maximize the software to see the creation in action and pinpoint what the issue is and why it is failing to create accounts.
