How to Fix Read-Only Word and Excel on Mac (Microsoft 365)
Question details
The user is experiencing a read-only issue in Word and Excel on a Mac, preventing document editing despite being signed into a Microsoft 365 account.
- Product
- Microsoft 365
- Device & OS
- macOS
- Scenario
- Attempting to edit documents in Word or Excel on a Mac using a Microsoft 365 organizational or personal account.
- Observed behavior
- Word and Excel open files in read-only mode, allowing the user to view the documents but restricting any editing, formatting, or saving modifications.
Ensure your Mac is connected to the internet and save any open work locally before attempting to modify your Microsoft 365 licensing or macOS Keychain settings.
Verify License and Remove Activation Data
Check your Microsoft 365 license status and clear corrupted activation data from your Mac's Keychain to restore editing permissions.
Read-only access generally occurs when Office is activated with an account that lacks the required desktop license, or when local activation files are corrupted. Clearing the old license files forces Office to re-authenticate properly.
Sign in to the Microsoft 365 portal, go to 'My Account', and select 'Subscriptions'. Verify that your account includes 'The latest desktop version of Office'. If it is missing, contact your IT administrator to assign it.
If the license is active, sign out of all Microsoft Office applications on your Mac. Then, open 'Keychain Access' from your Utilities folder and delete any entries containing 'Microsoft Office'.
Download and run the official Microsoft Office license removal tool to completely clear old activation data from your Mac.
Restart your Mac, open Word or Excel, and sign in again with your Microsoft 365 credentials to activate the software and restore editing access.
Completely Uninstall and Reinstall Office
If clearing the license data does not resolve the read-only issue, a clean installation of Office may be required.
Test with a New macOS User Account
Creating a new user profile helps determine if the read-only issue is caused by local profile corruption rather than a widespread licensing error.

Frequently Asked Questions
Why does my Microsoft 365 subscription only allow read-only access on my Mac?
This usually happens if your Microsoft 365 account only includes a web-based license, rather than 'The latest desktop version of Office'. It can also occur if your Mac's local activation data in the Keychain becomes corrupted and fails to authenticate your editing permissions.
Will running the Office license removal tool delete my documents?
No, the Microsoft Office license removal tool only removes the activation and licensing files from your Mac's system folders. Your personal documents, spreadsheets, and data will remain completely safe and untouched.
How do I check if my Microsoft 365 account has the correct desktop license?
Log in to the Microsoft 365 online portal, navigate to 'My Account', and select 'Subscriptions'. Look for 'The latest desktop version of Office' in the list of services. If it is missing, you will need to contact your IT administrator to have it assigned to your account.
Can I edit Word and Excel files on Mac without a Microsoft 365 subscription?
Yes. If your subscription expires or you encounter persistent license issues, you can use alternative software like WPS Office. It allows you to open, edit, and save your .docx and .xlsx files for free without needing an active Microsoft subscription.
