Quick answer
The thumbnail pane may be collapsed or narrowed rather than missing. Return to Normal view and inspect the left edge of the editing window.
Understand the issue
Do not rebuild slides because the navigation pane is hidden. Use the visible slide count and current slide content to confirm the presentation still contains your work. The desktop and web versions can offer different pane controls.
Step-by-step checks
- Switch to Normal view.
- Look for the collapsed thumbnail bar or narrow pane divider.
- Expand the pane and select a few slides to confirm navigation.

Check the presentation in the format people will actually use
Save a copy of the presentation before changing layout, output settings or embedded media. Note the PowerPoint version and whether the deck depends on external fonts, linked files or an online service. A presentation that works on the author’s computer may rely on something not included in the delivered file.
Choose representative slides for testing: a title slide, one with dense text, one with an image or chart and any slide containing media. Review them at presentation size rather than only in the editing thumbnail pane. If a change affects slide dimensions or printing, inspect both the application preview and the physical display or printer that will be used.
Reopen the delivery copy and run the intended workflow from beginning to end. Check readable text, complete images, working media and the correct slide order. For a PDF or handout, verify that export settings match the purpose; an editing file, projected show and printed handout are separate outputs. Retain the original deck and record any linked assets that recipients must also receive through an approved sharing method.
Before you finish
- Original deck preserved
- Representative slide types selected
- Linked and embedded content distinguished
- Slideshow, export or printed result tested

Frequently asked questions
Does collapsing the thumbnail pane delete slides?
