Solution 1Recommended

Verify Subscription and Re-apply Password Protection

Ensure your Microsoft 365 Personal subscription is active and apply the correct encryption settings through the File Info menu.

Even on personal accounts, Excel may restrict security features if it cannot verify an active Microsoft 365 subscription.

Additionally, it is important to choose the right protection level, as workbook protection and file encryption serve different purposes.

1
Check Subscription Status

Open Excel, click on 'File' in the top ribbon, select 'Account', and verify that your Microsoft 365 Personal subscription is active under the Product Information section.

2
Access Workbook Protection

Navigate to 'File', then click on 'Info'. Look for the 'Protect Workbook' dropdown menu.

3
Encrypt File

Select 'Encrypt with Password' from the dropdown list, type your desired password, and confirm it to require a password every time the file opens.

4
Protect Structure

Alternatively, select 'Protect Sheet' to restrict editing on specific cells, or choose 'Protect Workbook' to prevent structural changes like adding or deleting sheets.

Verify Subscription and Re-apply Password Protection
Password Recovery: If you lose or forget the password used for encryption, Microsoft Excel cannot recover it for you. Keep a secure record of all document passwords.

Frequently Asked Questions

Why does Microsoft 365 Personal show an 'organization's administrator' error?

This error can occur on personal non-enterprise accounts due to glitches in Microsoft's 'connected experiences' privacy settings, corrupted Office configurations, or conflicting third-party add-ins overriding default permissions.

What is the difference between Protect Workbook and Encrypt with Password?

'Encrypt with Password' locks the entire file, requiring the user to enter a password just to open and view the document. 'Protect Workbook' simply locks the structure of the workbook (like adding, moving, or deleting sheets) but allows users to open and view the file without a password.

Can I remove a password from an Excel file if it's no longer needed?

Yes, provided you know the current password. Open the encrypted file, go to File > Info > Protect Workbook > Encrypt with Password, delete the existing password from the text box so it is blank, and click OK.
