Microsoft verification codes not arriving at Gmail – error 7q6ca

Stop requesting codes for at least 24 hours, then make one attempt from a familiar device and network; repeated requests can trigger or extend a temporary verification-send block.^1^

An official definition for error 7q6ca is not published in the available Microsoft guidance, so it should be treated as part of the failed sign-in/verification flow—not proof of a Gmail or Windows 11 fault.

After the waiting period

1. Use a device, browser, and network previously used with this Microsoft account.
2. Request one code.
3. If available, select Sign in another way, Try another verification method, or I don’t have any of these.
4. Choose an existing registered method such as Microsoft Authenticator, a passkey, phone, or recovery email.

Trying the account’s other email alias does not necessarily provide another verification route. Microsoft sends email codes only to the primary alias or an email already registered as a way to verify sign-in.^1^

Since Inbox, Spam, All Mail, and Gmail filters have already been checked, there is no need to repeat those checks. If desired, one final targeted Gmail search can determine whether Microsoft delivered anything:

from:(accountprotection.microsoft.com)

That is Microsoft’s documented domain for account notifications and verification messages.^2^

If no registered method works

The next route depends on whether the password is known:

• Password known: At Verify your identity, select I don’t have any of these, then replace the security information. Microsoft imposes a 30-day wait before the replacement information can be used to sign in. Using recovered old security information during that period cancels the pending replacement.^3^
• Password forgotten or no security method accessible: Use the Microsoft account recovery form at https://account.live.com/acsr. Supply an alternate contact address and as much account history as possible, including old passwords and other requested account details. Microsoft’s sign-in guidance also directs personal-account users to the recovery form and Sign-in Helper.^4^
• Still blocked after waiting: Use the Sign-in Helper referenced on the same support page. It checks the account details and presents the recovery or support options available for that account.^4^

Microsoft Support can help identify the available recovery path, but agents cannot send a verification code, issue a password-reset link, or change account security details on the user’s behalf.^3^

After access is restored, add at least one independent sign-in method under Microsoft account → Security → Advanced security options → Add a new way to sign in or verify so access does not depend solely on Gmail.
