The error “This section cannot be edited because it’s in an archive format” appears in OneNote when you try to type, paste, or modify content in a notebook section that has been locked into a read-only or legacy format. This commonly happens with old OneNote notebooks, imported backups, shared notebooks, or notebooks created in earlier OneNote versions.
In most cases, this issue is not caused by corruption. Instead, it occurs because the section is stored in an outdated format, marked as read-only, synced incorrectly, or opened from a non-editable location. The steps below will help you restore editing access safely.
How to Fix “This Section Cannot Be Edited Because It’s in an Archive Format” in OneNote
Follow the steps below in order. After each step, check whether the section becomes editable before moving on.
1. Check Which OneNote Version You Are Using
Editing behavior depends on the OneNote version.
- Open Microsoft OneNote
- Click Settings > About (or File > Account)
- Confirm whether you are using:
- OneNote for Windows (Microsoft Store / Microsoft 365)
- OneNote 2016 (desktop version)
Older archive sections often open as read-only in newer OneNote apps.
2. Make a Copy of the Archived Section (Most Effective Fix)
Archived sections cannot be edited directly, but copies can.
- Right-click the archived section tab
- Select Move or Copy
- Choose a different notebook or a new location
- Check Copy instead of Move
- Click Copy
The copied section is usually converted into an editable format automatically.
3. Move the Section to a Modern Notebook Location
Some archive sections remain locked due to their storage location.
- Right-click the affected section
- Select Move or Copy
- Move it to a notebook stored on OneDrive
- Wait for sync to complete
Local-only or legacy locations can force archive mode.
4. Convert the Notebook by Creating a New Notebook
Entire notebooks created in older formats may cause this issue.
- Create a new notebook in OneNote
- Right-click each archived section
- Choose Move or Copy
- Copy sections into the new notebook
- Verify that sections are editable
This effectively converts the notebook to the latest format.
5. Check If the Notebook Is Opened as Read-Only
Read-only access prevents editing.
- Click File > Info (OneNote desktop)
- Check notebook status
- If it shows Read-only, close it
- Reopen the notebook from OneDrive directly
Read-only mode often appears when opening notebooks from backups or shared folders.
6. Open the Notebook in OneNote 2016 (If Available)
OneNote 2016 can sometimes edit archived sections.
- Install OneNote 2016 if not already installed
- Open the notebook in OneNote 2016
- Try editing the archived section
- If editable, copy content into a new section
This works for very old OneNote archive formats.
7. Check Sharing and Permission Settings
Limited permissions can lock sections.
- Open the notebook in OneDrive
- Click Share
- Make sure you have Edit permissions
- Remove and re-add yourself if needed
View-only access causes archive-style restrictions.
8. Make Sure the Notebook Is Fully Synced
Sync issues can falsely trigger archive mode.
- Click Sync status in OneNote
- Resolve any sync errors
- Wait until sync shows Up to date
- Restart OneNote
Incomplete sync can prevent edits.
9. Copy Pages Instead of Sections (Alternative)
If only one section is locked:
- Open the archived section
- Right-click individual pages
- Select Move or Copy
- Copy pages into a new editable section
This avoids dealing with the section format itself.
10. Avoid Editing OneNote Backup Files Directly
Opening .onepkg or backup folders causes archive mode.
- Do not open notebooks directly from:
- Backup folders
- External drives
- Email attachments
- Always restore notebooks into OneNote first
- Then edit from the restored copy
Backup files are read-only by design.
Final Thoughts
The “This section cannot be edited because it’s in an archive format” message in OneNote usually appears due to legacy notebook formats, read-only locations, or permission restrictions, not data loss. In most cases, copying the section or pages into a new notebook instantly restores full editing access.
To avoid this issue in the future, always store notebooks on OneDrive, avoid editing backup files directly, and keep OneNote updated.
