Hi, I'm John! I will help you with this.

To help narrow down the issue:

  1. Are you using a personal Microsoft 365 or a work/school account?
  2. Do you see any error message when signing in?
  3. Is Office still opening, or does it say it’s expired?

In the meantime, if you haven’t already:

On the affected device, please open any Office app (like Word or Excel).

Go to File > Account.

Check if it shows “Signed in” or “Product Information.”

If it says “Sign in,” please sign in using the same Microsoft account you used for Office 365.

If it shows “Not licensed,” click Change license and sign in again.

After that, open Settings > Update & Security > Windows Update and check for updates.

If the issue persists, please provide more details by answering my questions.

    To reconnect your device to your Office 365 account, you can follow these steps:

    1. Check Your Internet Connection: Ensure that your device is connected to the internet.
    2. Sign In to Office 365: Open any Office 365 application (like Word or Excel) on your device. If prompted, sign in with your Office 365 account credentials.
    3. Check Account Settings: Go to Settings > Accounts > Access work or school. Make sure your Office 365 account is listed there. If it is not, you may need to add it.
    4. Reconnect the Account: If your account is listed but not connected, select it and choose Reconnect or Connect. Follow the prompts to complete the process.
    5. Update Office 365: Ensure that your Office 365 applications are up to date. You can do this by opening an Office app, going to File > Account > Update Options, and selecting Update Now.
    6. Restart Your Device: Sometimes, a simple restart can help establish the connection.

    If you continue to experience issues, you may want to run the Microsoft 365 sign-in troubleshooter for further assistance.
