Repair Microsoft Office via Apps and Features

Open Windows Settings

Click the Start menu and go to 'Settings', then select 'Apps' and navigate to 'Apps & features'.

2
Locate Microsoft Office

Scroll down the list of installed applications to find your version of Microsoft Office or Microsoft 365.

3
Modify the Installation

Click on the Microsoft Office application and select the 'Modify' button. If prompted by User Account Control, click 'Yes'.

4
Run the Repair Tool

Choose 'Online Repair' (or 'Quick Repair' as a first step) and click 'Repair'. Follow the on-screen prompts to complete the process.

Restart and Test

Frequently Asked Questions

Why am I seeing a 'Due to organizational policies, you can't access these resources' error?

This error usually occurs when your company's IT department implements Conditional Access policies in Microsoft 365. These policies might restrict access based on your network location, device compliance status, or account permissions.

Will repairing Office delete my Excel files?

No, repairing Microsoft Office through the Apps & features menu only fixes the application installation files and registry keys. Your personal Excel workbooks and Word documents will remain safely untouched on your hard drive.

How do I know if an add-in is causing my Excel access issues?

You can launch Excel in Safe Mode by holding the Ctrl key while clicking the Excel shortcut. If the application opens normally and runs without issues in Safe Mode, a third-party add-in is likely causing the problem.

What should I do if the Office Online Repair doesn't work?

If the Online Repair fails, you may need to use the Microsoft Support and Recovery Assistant (SaRA) tool to completely uninstall and reinstall Office, or check with your IT administrator if a security policy is blocking the software activation.
