Sending, receiving, and organizing email in Outlook.com
This is usually a temporary security block triggered by unusual activity, repeated sign-up attempts, or the network or verification method being used.
Try these steps in order:
- Stop trying for at least 24 hours. Repeated attempts can keep the block active. If it still fails after 24 hours, wait longer if possible, up to 1 week.
- Try a different network. Switch between Wi‑Fi and mobile data, or use another trusted Wi‑Fi connection.
- If another verification method is available, use that instead.
- If creating a brand-new Microsoft account, try again from the Microsoft sign-up page: https://signup.live.com.
- If the address might already be tied to a Microsoft account, check it by going to https://account.microsoft.com and entering the email address:
- If a password prompt appears, it is already a Microsoft account.
- If the message says the account does not exist, it is not currently a Microsoft account.
- If the account is an Outlook.com account that became blocked, reset the password to unblock it.
If an Outlook.com or OneDrive mailbox is full, email sending and receiving can also be affected.
