Word "This modification is not allowed because the selection is locked": fix
Word shows this in the status bar when the part you are editing is protected. Usually someone turned on Restrict Editing for the document. To fix it, go to Review > Restrict Editing and click Stop Protection at the bottom of the pane. If Word asks for a password, you need it from the author. Other causes are a document Marked as Final, a locked content control or an unactivated copy of Office.
What this message means
Word blocks the edit because the text under your cursor is flagged as read only. That flag can come from several places. The most common is document protection (Restrict Editing), which can lock the whole file or leave only some regions editable. Word also shows the message when a file is Marked as Final, when you type inside a content control that is set to "Contents cannot be edited", and when Office has dropped into reduced functionality mode because it is not activated. The file itself is not damaged. You need to find the lock that applies to your case and switch it off, or get permission from the person who set it.
Common causes
| Cause | How to tell |
|---|---|
| Restrict Editing (document protection) is on | Review > Restrict Editing opens a pane with a Stop Protection button at the bottom. If only parts of the file are editable, those regions may show yellow highlighting or brackets, and you can type in them but nowhere else. |
| The document is Marked as Final | A yellow bar at the top reads "Marked as Final" with an Edit Anyway button. File > Info shows Protect Document highlighted with a note that the document has been marked as final. The ribbon is mostly greyed out. |
| A content control is locked, or the content is grouped | The lock only applies to one box, field or block (often in forms and templates). Clicking it shows a labelled frame or handle. Text outside that box can be edited normally. |
| Office is not activated or the subscription has expired | The error appears in every document, including new blank ones. The title bar or a banner says "Unlicensed Product" or "Product Activation Failed", and File > Account does not show an active licence. |
| Your Normal.dotm template has protection applied | Every new blank document is locked, but Office shows as activated. Opening Normal.dotm and checking Review > Restrict Editing shows Stop Protection. |
| The file is open by someone else or set to open read-only | The title bar shows "Read-Only", or Word said the file is locked for editing by another user when you opened it. This is common with files on shared drives, SharePoint or OneDrive. |
How to fix it
1. Stop document protection (Restrict Editing)
Word for Microsoft 365, 2024, 2021, 2019 and 2016 on Windows. On Mac, use Review > Protect Document (or Review > Restrict Editing in newer builds) and turn protection off in that dialog.
- Open the Review tab.
- In the Protect group, click Restrict Editing. The Restrict Editing pane opens on the right.
- Click Stop Protection at the bottom of the pane.
- If Word asks for a password, enter it. Without the password you have to ask the document's author to remove protection or send an unprotected copy.
- Save the file so it stays unprotected.
2. Edit only the regions you are allowed to change
Documents where the author deliberately left some sections editable (forms, contracts, templates)
- Go to Review > Restrict Editing.
- In the pane, click Find Next Region I Can Edit to jump to the next editable section, or Show All Regions I Can Edit to highlight all of them.
- Make your changes inside those regions only. Anything outside them stays locked by design.
3. Turn off Mark as Final
Word for Windows. Word for Mac can open Final documents and shows Edit Anyway, but cannot set Mark as Final itself.
- If a yellow Marked as Final bar is showing, click Edit Anyway.
- Or go to File > Info > Protect Document and click Mark as Final to toggle it off.
- Save the document.
4. Unlock a content control or ungroup content
Word for Windows and Mac. Requires the Developer tab (Windows: File > Options > Customize Ribbon > tick Developer. Mac: Word > Settings > Ribbon & Toolbar > tick Developer).
- Click inside the box or field you cannot edit.
- On the Developer tab, in the Controls group, click Properties.
- Under Locking, clear "Contents cannot be edited" (and "Content control cannot be deleted" if you want to remove the box). Click OK.
- If the content is grouped, select it and click Developer > Group > Ungroup.
- If Properties is greyed out, first stop document protection using the fix above.
5. Activate Office or remove an unlicensed copy
Microsoft 365 and Office 2016 or later on Windows and Mac. The Installed apps path is Windows 11 (Windows 10: Settings > Apps > Apps & features).
- In Word, go to File > Account (Mac: Word > About Word or the Account button) and check the product information.
- If it says activation is needed, click Sign in or Activate and use the Microsoft account that owns the licence.
- If the subscription expired, renew it and restart Word.
- On Windows, open Settings > Apps > Installed apps and search for Office. If two versions are installed, uninstall the one you do not have a licence for.
- Restart Word and try editing again.
6. Fix a protected Normal.dotm template
Word for Windows (template in %appdata%\Microsoft\Templates). On Mac the file is in ~/Library/Group Containers/UBF8T346G9.Office/User Content/Templates.
- Close Word completely.
- Press Windows + R, type %appdata%\Microsoft\Templates and press Enter.
- Rename Normal.dotm to Normal.old.
- Open Word. It creates a fresh, unprotected Normal.dotm automatically.
- Test a new blank document. Your custom styles and macros stored in the old template will be gone, so keep Normal.old in case you need to copy them back.

If Stop Protection asks for a password nobody knows, ask the author for an unprotected copy. On a work computer, contact your IT team, since the file may also carry sensitivity labels or IRM permissions that only an admin can change. If the file is on OneDrive or SharePoint, open it in the Word desktop app instead of Word for the web and check that nobody else has it open. If the error appears in every document even after activation, run Office's repair (Windows: Settings > Apps > Installed apps > Microsoft 365 > Modify > Quick Repair, then Online Repair) or contact Microsoft Support from File > Account.
Questions people ask
How do I unlock a locked Word document without the password?
Word has no built-in way to bypass a Restrict Editing password. Ask the author for the password or an unprotected copy. If you only need the text, you can usually copy it from the editable view into a new document.
Why is every Word document locked, even new ones?
The two usual reasons are an unactivated or expired Office licence (check File > Account) and a protected Normal.dotm template. Renaming Normal.dotm so Word rebuilds it fixes the second one.
Why can I edit some parts of the document but not others?
The author used Restrict Editing with exceptions, or put the text in locked content controls. Use Review > Restrict Editing > Show All Regions I Can Edit to see which parts you are allowed to change.
Where is the Stop Protection button if I can't see it?
It sits at the bottom of the Restrict Editing pane (Review > Restrict Editing). If the pane has no Stop Protection button, the document is not protected, so check for Mark as Final, a locked content control or an activation problem instead.
Is this the same as "You can't make this change because the selection is locked"?
Yes. Newer versions of Word show that wording for the same situation, and the causes and fixes are identical.
