I have a corrupt powerpoint that I need urgently for tomorrow and it will not open I need urgent help

Hi @Diane Stanton

To help determine whether the file can be recovered, could you let me know:

• Do you receive a specific error message when trying to open the presentation? If so, could you share a screenshot?
• Is the file stored locally on your Mac or in OneDrive?
• Can you open other PowerPoint presentations normally, or does this happen with every file?

In the meantime, you can try the following:

• Make a duplicate of the original file and try opening the copy. Keep the original unchanged while troubleshooting.
• Open PowerPoint, then select File > Open and browse to the presentation instead of double-clicking the file.
• If the file is stored in OneDrive, try opening it in PowerPoint for the web to see whether the web version can read it.
  If the file is stored locally on your Mac, upload a copy of the presentation to OneDrive and try opening it in PowerPoint for the web. Sometimes the web version is able to open a presentation that the desktop application cannot.
• Check PowerPoint > File > Open Recent > Recover Unsaved Presentations, if that option is available in your version of PowerPoint.
