Managing personal Outlook.com account settings, security, and privacy
Hello
This message is usually triggered by some unusual activities from your device, IP address, etc. Microsoft explains it here:
https://support.microsoft.com/en-us/accounts-billing/manage/account-creation-has-been-blocked
The official recommendations are: switching devices and browsers, clearing browser cache, enabling JavaScript, and avoiding private browsing
I am seeing an increasing number of threads lately from users reporting the same issues here. Some users have reported using the following methods worked for them.
Stop retrying for at least 24 hours to avoid repeatedly triggering the security restriction.
On a smartphone, turn off Wi-Fi and use cellular data. Disable any VPN or proxy.
Open a normal browser window (not Incognito/InPrivate), preferably using a different browser or device from the original attempt.
Go directly to https://signup.live.com and create the Microsoft account there, rather than through OneDrive.
