How to Fix Excel Stuck on Signing In and Cloud Upload Issues
Question details
Users are unable to access their Microsoft Excel accounts or sync files because the application freezes during the sign-in process and cloud uploads fail.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Attempting to log into an Office account within Excel or trying to sync and upload a newly edited spreadsheet to Microsoft Cloud services.
- Observed behavior
- Excel remains infinitely stuck on the signing-in prompt, and spreadsheet cloud uploads remain pending or fail completely.
Verify that your internet connection is stable and ensure your Microsoft 365 subscription is currently active, as expired licenses often trigger authentication loops.
Update Microsoft Office Applications
Installing the latest Microsoft 365 updates can resolve known bugs that cause sign-in freezes and cloud upload failures.
Microsoft frequently releases patches for Office applications to fix authentication and syncing bugs. Forcing a manual update can bypass the glitch causing Excel to hang.
Launch Microsoft Word or another Office application that is currently working and not stuck on a sign-in screen.
Click on 'File' in the top-left corner, then select 'Account' from the bottom of the left-hand menu pane.
Under the Product Information section, click on 'Update Options' and select 'Update Now' from the dropdown menu.
Wait for the updates to download and install completely. Once finished, restart your computer and open Excel to see if the sign-in issue is resolved.
Reset the Office Activation State
If updating doesn't work, resetting the Office activation state clears corrupted credentials that block the sign-in process.
Switch to WPS Office for Seamless Cloud Syncing

- 3. Sync to WPS Cloud: Sign in to your free WPS account to automatically save and sync your work across all your devices.
Frequently Asked Questions
Why is Excel stuck on the signing-in screen?
This usually happens due to corrupted cached credentials, outdated Microsoft Office software, or network issues blocking communication with Microsoft's authentication servers.
How can I save my Excel file if the cloud upload fails?
If the cloud upload is hanging, go to File > Save As, and choose a local directory on your PC (like your Desktop or Documents folder) to save a local copy immediately.
Does resetting the Office activation state delete my spreadsheets?
No, resetting the activation state only clears the license and login credentials stored on your computer. It does not affect, modify, or delete any of your personal files or spreadsheets.
Can a third-party antivirus cause Excel cloud upload issues?
Yes, some strict antivirus programs or firewalls can block Excel from accessing the internet, preventing it from signing in or uploading files. Try temporarily disabling your firewall to see if the issue resolves.
