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.
On Windows 11 with Microsoft 365, the most likely cause is that the specific Segoe font variant in the presentation is not being embedded, even though it is available for editing on the PC.
Use this check-and-fix path:
- In PowerPoint, go to File > Options > Save.
- Under Preserve fidelity when sharing this presentation, turn on Embed fonts in the file.
- Prefer Embed all characters rather than embedding only the characters used. This is better if the file will be edited by others.
- Save the presentation again.
If the error still appears, check whether the font is embeddable in Windows:
- Open Control Panel > Fonts.
- Select the Segoe font being used.
- Check the Font embeddability setting.
Not all TrueType fonts can be embedded. Font creators can mark fonts as Non-embeddable, Preview/Print, Editable, or Installable. If the font is not embeddable, PowerPoint can use it for authoring but cannot save it into the presentation file.
Also note:
- Office cloud fonts usually do not need embedding because they download automatically when needed.
- If the presentation uses a font that other devices do not have, those devices may show a substitute font unless the font can be embedded.
- Segoe UI is supplied by Windows and is also available within Office applications.
If the issue is happening with a specific Segoe family member rather than Segoe UI generally, verify that exact font file is the installed Windows/Office version and that its embeddability allows embedding.
