Hello, thank you for reaching out to Microsoft Q&A.
- May I know which Office edition you are trying to register? (e.g., Office Home 2024, Office 365, etc.)
- Also, is this the first time you are trying to activate the pre-installed Office that came with your device?
- Close the Office applications.
- Go to Settings > Accounts > Your info. Ensure you've signed in with your Microsoft account on the device, not a local account.
- Next, click Windows + R key, type services.msc, and click ok.
- Locate 'Microsoft Sign-in Assistant Service', right-click, and restart the service.
- Open office apps and sign in with your Microsoft account again.
If you're still having issues, switch your PC to a different Wi-Fi network, such as a Mobile hotspot, and see if you can sign in successfully to the Office applications.
