What is this error message [7q6ca] referring to?

The 7q6ca / 2147483661 error is a generic Microsoft authentication error and has been reported with both browser and Microsoft app sign-ins.

Since you're being asked to verify your identity, I'd first try an InPrivate/Incognito window and sign in again. If it still fails, clear the Microsoft sign-in cookies/cache and temporarily disable any VPN, proxy, or browser extensions that could interfere with the verification page.

Also make sure Windows Date & time is set to automatic and synced.

If it works from another browser or device, that would point more toward a local browser/session issue rather than your password, phone number, or email being incorrect.

I understand how confusing this is, Lela.

Unfortunately, [7q6ca] hasn't been documented by Microsoft as an official issue code, so I cannot say for sure what's happening. There have been similar reports with the same sign-in scenarios though, and here are some suggestions from other users:

• Sign into your account on https://account.microsoft.com/ and make sure it's working.
• Open Microsoft Edge > click the three-dot > New InPrivate window, then try the verification again.
• If it works there, clear the cookies and cached data in your regular Edge profile.
• If it still fails, try the verification from another browser/device/network if possible (e.g. mobile hotspot).
• Sign out of your Windows > sign back in but with your account password (not Windows Hello PIN, Face...)

If the same error still occurs on your account after all the checks above, I recommend contacting Microsoft Support directly so they can check why the issue still applies to your account or device:

1. Visit Contact Us - Microsoft Support > Sign in
2. Enter / choose an issue > Get Help to make request
3. Scroll down > click Contact Support to connect to an agent
4. Select a category > continue and you should reach the chat option.
5. If you don't see it, go through another category (e.g. Billings and payments...)

Note: The support contact team only works at certain times, so if the last window shows that it's unavailable, try opening it again the next day. If you prefer phone support, you can leave a phone number. This way, they can call you and help you.

I hope the issue would be resolved soon.
