Account creation has been blocked

Seven days is the longest published waiting period for this type of block, so waiting longer is not a documented remedy; make one attempt through Windows 11’s built-in account-creation flow, then escalate to Microsoft Support if that is also blocked.

Create the child account through Windows 11

Since changing device, browser, VPN status, and waiting seven days did not help, do not repeat those same measures or make multiple rapid attempts.

1. On the Windows 11 PC, open Settings.
2. Select Accounts → Other users.
3. Under Add other user, select Add account.
4. Select I don’t have this person’s sign-in information.
5. Choose the option to create a new Microsoft account/new email address.
6. Enter your son’s correct date of birth and other details.
7. When prompted, sign in with the parent or guardian’s Microsoft account to complete consent.

Microsoft documents this as a supported way to create a Microsoft account from Windows. A parent or guardian must sign in to finish setting up a child’s account.^1^^2^

If the intended address was previously used for any Microsoft account—even one closed long ago—it cannot be reused. In that case, choose a genuinely new address.^2^

Is seven days “a while”?

Yes. Microsoft’s published guidance says:

• Waiting one day can sometimes clear a block.
• Do not make repeated attempts because that may reset the time lock.
• If 24 hours is insufficient, wait longer, up to one week.^3^

You have already completed that maximum published waiting period. Microsoft does not publish a guaranteed expiry time for every account-creation block, so there is no supported basis for recommending another specific number of days.

Temporary versus permanent blocks

Microsoft identifies these possible triggers:

• Sign-up activity assessed as unusual or risky.
• Excessive or repetitive requests involving phone numbers or alternative email addresses; these can cause temporary or permanent blocks.
• Terms-of-service violations.
• Heavy compromised traffic originating from a geographic area, which Microsoft says is rare and normally resolves automatically.^3^

Documented policy violations include automated scripts or bots creating accounts, reusing or spoofing information across multiple accounts, spam, phishing, malware, and creating multiple accounts to evade Microsoft policies.^4^

The error alone does not establish that your son has a permanent block or that any violation occurred. Microsoft does not expose the exact risk signal that triggered an individual sign-up rejection.

If the Windows flow is also blocked

Stop further attempts and contact Microsoft Support:

1. Open Microsoft’s support page.
2. Select the Personal account tab.
3. Use Get Help and enter:
   “Child Microsoft account creation blocked after seven days with no retries; alternate Windows 11 creation flow also blocked.”
4. Request the available account-support or chat route.

Microsoft states that the available support method depends on the product and issue. Support agents cannot directly access or change account details, but the support workflow can identify available account-specific options.^5^

Once the account is created, add it to your Microsoft family as a Member. Under-age users will be prompted for adult consent.^6^
