A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
After doing some research, the error "Some of your fonts cannot be saved with the presentation" typically occurs when PowerPoint is unable to embed one or more fonts used in the presentation. This can be caused by font embedding restrictions, a corrupted slide, or content imported from other sources that contains unsupported fonts.
Please try the following troubleshooting steps:
1/Check if font embedding is enabled
- Open the presentation in PowerPoint.
- Go to File > Options > Save.
- Under Preserve fidelity when sharing this presentation, select Embed fonts in the file.
- Choose Embed all characters (best for editing by other people).
- Save the presentation again.
2/If font embedding is enabled, try Save as > Browse > Tools button > Save options > Embed fonts to Off.
3/Check for a problematic slide
- Create a new blank presentation.
- Copy slides from the original presentation into the new file one at a time, saving after each addition.
- If the error appears after adding a particular slide, review that slide for unusual fonts, charts, or imported content. I know this will be a lot of work if the presentation has many slides, however, this is the most effective way to track which slide is having a problem.
If the issue continues after completing the steps above, please let me know which specific Segoe font variant is being used and whether the issue occurs in a brand-new presentation. This will help determine whether the font itself has embedding restrictions.
