cannot receive code sent to my gmail account

Check Gmail for messages from @accountprotection.microsoft.com, then use Microsoft’s security-information replacement process if no code arrives.

Check Gmail delivery

1. In Gmail’s search box, enter:

      from:(accountprotection.microsoft.com)
   

2. Check Spam, Trash, All Mail, and any category tabs.
3. Open Gmail → Settings → See all settings → Filters and Blocked Addresses. Remove any rule that blocks, deletes, forwards, or archives messages from accountprotection.microsoft.com.
4. Add accountprotection.microsoft.com as a trusted sender. Genuine Microsoft verification-code emails come from that domain.^1^
5. Verify that the first two characters of the masked Gmail address shown on Microsoft’s verification page match the intended address.

Request one new code afterward. Do not repeatedly request codes: excessive attempts can trigger a temporary block. If several requests have already been made, stop trying for at least 24 hours; Microsoft notes that some blocks can take longer—up to one week—to clear.^1^

If Gmail is your only verification option

At the Verify your identity screen:

1. Select I don’t have any of these.
2. Supply a new email address or other requested security information.
3. Follow the prompts to replace the inaccessible verification method.

Replacing all security information starts a 30-day waiting period before sign-in is restored. If access to the original Gmail method is recovered during that period, using it to sign in cancels the replacement request.^1^

If another verification method is displayed—such as a mobile number—select that instead.

If you also forgot the Hotmail password

Use the Microsoft account recovery process. Provide:

• A working email address where Microsoft can contact you.
• Previous passwords.
• Exact subject lines and contacts from the Hotmail account.
• Other requested account details.

Complete it, if possible, from a device and location previously used with the account. Microsoft sends the result to the contact address within 24 hours; unsuccessful requests can be retried up to twice daily.^2^

The recovery form cannot recover an account when two-step verification was enabled and none of its registered verification methods are accessible. Microsoft support also cannot manually send a code, bypass verification, or change account details.^2^
