How to Fix OneNote Embedded PowerPoint File Not Found Error
Question details
The user is unable to open a PowerPoint presentation embedded in OneNote after the initial attempt due to a file-not-found error.

- Product
- Microsoft OneNote and PowerPoint
- Device & OS
- not provided
- Scenario
- Attempting to open an embedded PowerPoint file from within a OneNote notebook multiple times.
- Observed behavior
- The embedded PowerPoint file opens successfully the first time but displays a file-not-found error on subsequent attempts, while embedded Word and Excel files continue to open normally.
Ensure you have the original, standalone PowerPoint file saved on your local hard drive so you do not lose any data while removing restrictions or re-embedding the file.
Remove Editing Protection from the PowerPoint File
Removing edit protection or passwords from the original PowerPoint file before embedding it resolves temporary cache conflicts in OneNote.
OneNote extracts embedded files to a temporary folder when you open them. If a PowerPoint file has editing restrictions applied, OneNote may fail to manage this temporary file properly on subsequent launches, resulting in the file-not-found error.
Launch Microsoft PowerPoint and open the original source file outside of OneNote.
Navigate to 'File' > 'Info', click on 'Protect Presentation', and remove any passwords or 'Mark as Final' restrictions.
Save the unprotected PowerPoint file to a local folder on your computer.
Go back to OneNote, delete the problematic embedded file, and insert the newly saved, unprotected PowerPoint file into your notebook.

Disable Conflicting OneNote Add-ins
Third-party add-ins can sometimes interfere with OneNote's ability to trigger external applications like PowerPoint.
Test with a New Windows User Profile
Creating a new user profile helps determine if the issue is caused by corrupted temporary file permissions on your current Windows account.

Frequently Asked Questions
Why does this file-not-found error only affect PowerPoint and not Word or Excel?
PowerPoint files often handle editing protections and 'Marked as Final' metadata differently than Word or Excel. When embedded, these specific PowerPoint protections can conflict with OneNote's temporary file management, causing OneNote to lose track of the extracted file.
Can I keep my PowerPoint file password-protected while embedding it in OneNote?
While it is possible to embed password-protected files, doing so frequently triggers the file-not-found error upon subsequent opens. It is highly recommended to remove the password protection before embedding the file to ensure reliable access.
Where does OneNote temporarily store embedded files when trying to open them?
When you open an embedded file, OneNote extracts it to a temporary folder located within your Windows user profile, typically found under AppData\Local\Temp. If permissions to this folder become corrupted, OneNote cannot locate the file it just extracted.
