Run a Microsoft Office Repair
Use the built-in Windows repair tool to fix isolated configuration or file corruption issues affecting Microsoft Excel.
When only one application in the Microsoft Office suite experiences connectivity issues, the application's specific configuration files might be corrupted. Running a Quick Repair is the fastest way to resolve this without needing an internet connection.
Open a working Office application like Microsoft Word. Navigate to File > Account and confirm the exact email address of the Microsoft 365 account you are trying to use in Excel.
Right-click the Windows Start button and select Apps and Features (or Installed Apps in Windows 11). Alternatively, you can open the Control Panel and navigate to Programs and Features.
Scroll down the list to find your Microsoft 365 or Office installation. Click on it, select Modify, and confirm the User Account Control prompt if it appears.
Select the 'Quick Repair' option and click Repair. Wait for the process to complete, then restart your computer, open Excel, and attempt to sign in again.
If Quick Repair does not fix the sign-in error, repeat the steps above but choose 'Online Repair'. This will thoroughly reinstall the Office suite components.
Sign Out and Clear Office Credentials
Remove cached account credentials that might be preventing Excel from authenticating properly.

Frequently Asked Questions
Why is only Excel experiencing sign-in issues while Word works perfectly?
Each Microsoft Office application maintains its own local cache and configuration files. If Excel's specific token or app data becomes corrupted or outdated, it can fail to connect to your account even while Word or PowerPoint successfully use their intact data.
Will running an Office Repair delete my Excel files?
No. Both Quick Repair and Online Repair only fix, replace, or update the Microsoft Office application files. Your personal spreadsheets, documents, and settings will remain completely untouched.
What is the difference between Quick Repair and Online Repair?
Quick Repair scans and replaces corrupted files using local data already on your computer, which is fast and does not require an internet connection. Online Repair uninstalls and completely reinstalls the Office suite by downloading fresh files from Microsoft's servers.
