Can't sign into copilot

Question

Can't sign into copilot

Ezra 40

I’m currently unable to sign in to Copilot. The interface says I’m not signed in, but it also doesn’t allow me to sign in. I’ve cleared cookies, tried incognito mode, refreshed the browser, and attempted alternate sign-in paths. I only have one device, so I can’t test elsewhere. There’s no error message—just a silent block.

I have had problems with Copilot since Microsoft Edge was updated about a fortnight ago. Since then, I have been unable to use the AI assistant. It tells me to log in, but nothing happens when I click the button. Only the "maybe later" button works.

Dear Ezra

Thanks for reaching out! Welcome to Microsoft Q&A. I'm Haien from Microsoft Q&A.

It sounds like a connection or authentication issue is preventing the Copilot service from properly verifying your identity, even if your browser's local data suggests you've cleared everything.

Here are some effective ways to work on:

Go to Settings > Accounts > Email & accounts and confirm your personal Microsoft account is listed. If Copilot is accessing the wrong account, try switching to your personal account in Settings > Accounts > Your info > Sign in with a Microsoft account instead.
Go to Settings > Apps > Installed apps > Find Microsoft Copilot in the list > Click the three dots (...) next to it > select Advanced options > First, try the Repair option. If that doesn't work, proceed with the Reset option.
Open the Get Help app, search for "Copilot license troubleshooter" > follow the steps to check for firewall or network blockers.

This does not help. It is an issue with the change in the UI. I have no way to actually sign in on the side bar. Previously there was.

Thank you for the response Haien. My case is quite similar. Everything is the same other than I cannot sign in, into the sidebar copilot. It has become a crucial part of my workflow and any help would be great. That's what I mean with the change in UI, there used to be an option to sign-in using the sidebar copilot, but it is gone now and I am not signed in. I'll go ahead and create a new thread.

P.S. by thread you mean ask a new question?

I have the same problem — now on three different machines (private, work, and the kids’ PC as well). On the login window the buttons are inactive.

I have carried out all the suggested steps, including a full reinstall, but without success. The app starts, then shows the login window with inactive buttons.

We are waiting for a prompt solution. (Until then, we will stick to the browser version…)

I found a workaround for it… As soon as the start page appears — but before the login window with the inactive buttons pops up — you have to immediately click on the glasses icon. With screen sharing and microphone activation, the interface logs in automatically and becomes usable. You’re welcome. 😉
