PowerPoint found a problem with content in the file. PowerPoint can attempt to repair the presentation.
Microsoft Microsoft Office
Severity: ModerateWhat Does This Error Mean?
This message means PowerPoint detected something inside the file that does not look right. It could be a small formatting issue, a broken link, or genuine file corruption. PowerPoint offers to repair it for you — and in most cases, the repair works fine with little or no content lost.
Affected Models
- Microsoft PowerPoint 2016
- Microsoft PowerPoint 2019
- Microsoft PowerPoint 2021
- Microsoft 365 PowerPoint
Common Causes
- The file was not saved correctly — for example, the PC lost power or crashed while saving
- The presentation contains embedded media files or fonts that are corrupted or missing
- The file was created in a much newer or much older version of PowerPoint
- The file was downloaded from the internet and Windows security has flagged it
- Embedded objects from Excel or Word inside the presentation are broken
How to Fix It
-
When the error appears, click Repair. PowerPoint will attempt to fix the file automatically and then open it.
This works in the majority of cases. Review the recovered presentation carefully to check all slides are present.
-
Right-click the file, select Properties, and look for an Unblock button at the bottom. Click Unblock if it is there, then try to open the file again.
Files downloaded from the internet are automatically blocked by Windows. Unblocking often stops this error from appearing at all.
-
Try opening the file in Google Slides. Go to slides.google.com, click the folder icon, and upload your .pptx file. If Google Slides opens it cleanly, download it back as .pptx.
Google Slides is surprisingly good at opening presentations that PowerPoint struggles with.
-
Change the file extension from .pptx to .zip and extract it. Inside you will find individual XML files and media. This lets you check if any specific elements are damaged.
PowerPoint files are actually ZIP archives in disguise. Opening the ZIP gives you access to the raw content, which can help identify what is broken.
-
Open a new blank presentation, then go to Home > New Slide > Reuse Slides. Browse to the damaged file and import slides one by one into the new presentation.
Reusing slides from a damaged file lets you rescue the content slide by slide, bypassing whatever is causing the error in the original file.
When to Call a Professional
If you click Repair and PowerPoint still cannot open the file, and the presentation is critical, try a professional recovery tool. Stellar Repair for PowerPoint is a paid tool that recovers content from heavily damaged files. For presentations stored on Microsoft 365 or SharePoint, check version history for an earlier clean copy.
Frequently Asked Questions
I clicked Repair and it opened, but some slides are missing. Can I get them back?
Possibly. Check if OneDrive, SharePoint, or a backup folder has an older copy of the file. If the file was emailed to you, look in your email for the original attachment. You can also try the Reuse Slides method above to import from the damaged original — sometimes it recovers slides that the automatic repair missed.
Why does PowerPoint only show this error on my computer but not my colleague's?
The most likely reason is that your version of PowerPoint is older. Newer PowerPoint features and effects cannot be displayed in older versions, which triggers a content error. Ask your colleague what version they are using and consider updating your Office installation.
How can I stop this from happening to future presentations?
A few good habits help: Always save using Ctrl + S regularly as you work. Use OneDrive or SharePoint so AutoSave is always on. Avoid embedding large video files directly — instead link to them. After creating an important presentation, email it to yourself as a backup.
