PowerPoint is not going away.
What is going away in the Microsoft 365 messaging is Publisher, not PowerPoint. If the concern came from a Microsoft email about apps changing in October 2026, that message refers to Publisher being removed from Microsoft 365. That does not mean PowerPoint will stop working.
For presentations in September and October:
- Existing PowerPoint presentations can still be used.
- If the files are in modern .pptx format, they are the normal PowerPoint format.
- If a presentation is saved in the older .ppt format, PowerPoint may open it in Compatibility Mode. In that case, some newer features can be unavailable or behave differently.
- When a .pptx file is saved as .ppt, PowerPoint runs the Compatibility Checker to warn about content that may not work correctly in earlier versions.
Best way to make sure current presentations work:
- Open the presentation in PowerPoint.
- Check whether the file is an older .ppt file.
- If it is, save it in the current .pptx format to avoid Compatibility Mode limitations.
- If needed, run the Compatibility Checker before sharing with people who might use older PowerPoint versions.
If an older Windows mobile app is being used, that is a separate issue: the PowerPoint Mobile UWP app is no longer supported after October 14, 2025. Alternatives listed are:
- PowerPoint on the web
- Desktop PowerPoint through Microsoft 365
- The Microsoft Copilot app on iOS or Android for mobile use
So the practical answer is:
- PowerPoint is still available and usable.
- Publisher is the app being removed from Microsoft 365 in October 2026.
- Current presentations should work, especially if saved as .pptx.
- If there is any doubt, open each important file now and resave older .ppt files as .pptx.
