Fix Blank Word and Excel Files After Microsoft 365 Sign-In
Question details
The user needs to open Word and Excel files that appear blank after repeated Microsoft 365 sign-in prompts.
- Product
- Microsoft 365 desktop apps: Word and Excel
- Device & OS
- not provided
- Scenario
- Opening a Word or Excel file from Microsoft 365 or OneDrive in a desktop app.
- Observed behavior
- The app repeatedly prompts for sign-in and then displays a blank document instead of the file content.
Check which account has access to the file in OneDrive Online and note the account shown under File > Account in Word or Excel. Test whether the issue affects one file or several files.
Match the Office and OneDrive accounts
Use the same account in the desktop app and OneDrive to resolve possible sign-in or access mismatches.
Open OneDrive Online in your browser, select the profile icon, and note the account used to access the file.
In Word or Excel, select File > Account and compare the signed-in account with the OneDrive account.
Under File > Account, sign out if the wrong account is active, then sign in with the account that has access to the file. Try opening the file again.
Open OneDrive Online in another browser or an InPrivate window, sign in with the same account, and try opening the file in the desktop app.
Remove cached Office credentials on Windows
Clear relevant saved credentials if the desktop app continues to request sign-in.
Repair Office and open the file from the desktop app
Try opening the file directly and repair the installation if the account and credential checks do not help.
Open Word and Excel Files with WPS Office
WPS Office is a free, lightweight alternative with a familiar interface for working with documents and spreadsheets. Open compatible Microsoft Office files to make moving between applications easier; it does not repair Microsoft 365 sign-in issues.
Frequently Asked Questions
Why does Word or Excel keep asking me to sign in?
The desktop app may be using a different account from the one that can access the OneDrive file, or cached credentials may be causing a sign-in issue. Compare the accounts in OneDrive Online and File > Account in the Office app.
How can I tell whether only one file is affected?
In Word or Excel, select File > Open and try another file. If other files open normally, check the affected file's access permissions and try opening it from OneDrive Online.
Where do I remove saved Office credentials on Windows?
Go to Control Panel > User Accounts > Credential Manager > Windows Credentials. Expand relevant MicrosoftOffice16_Data entries and select Remove, then sign in to Office again.
How do I repair Microsoft 365 on Windows?
Open Settings > Apps > Installed apps or Apps & features, find Microsoft 365 or Office, and select Modify or Repair. Follow the prompts and test the file again.
