- The sidebar has disappeared, stopped displaying slide thumbnails, or is missing specific options like Connect after the application was updated.

Restart Application and Check View Settings
Performing a fresh restart and verifying your view mode can resolve temporary interface glitches caused by a recent software update.
Software updates can sometimes temporarily disrupt the layout of your workspace. A system reboot combined with verifying the default view mode is the quickest way to restore missing panels.
Save your current file, close Microsoft PowerPoint completely, and restart your computer to clear out any temporary system caches.
Open your presentation, navigate to the "View" tab located on the top ribbon.
Click on "Normal" in the Presentation Views group. Slide thumbnails are designed to only appear in Normal view, not in Reading View or Slide Sorter.
Hover your mouse pointer on the far-left edge of the PowerPoint window. If the cursor changes to a double-headed arrow, click and drag it to the right to expand the hidden thumbnail pane.

Test File Specificity and Install Pending Updates
Determine if the issue is an application-wide bug and install any missing hotfixes provided by Microsoft.
Run the Microsoft 365 Repair Tool
Use the Windows built-in repair utility to fix corrupted installation files that might be preventing the sidebar from loading.

Frequently Asked Questions
Why did my PowerPoint slide thumbnail pane disappear after updating?
Software updates can sometimes reset custom interface configurations or introduce temporary display bugs. Additionally, the update might have inadvertently shifted the application out of 'Normal' view, or the sidebar divider might have been reset to the far-left edge of the screen.
Will running an Online Repair for Microsoft 365 delete my presentation files?
No. Repairing Microsoft 365 only scans and replaces the application's underlying program files and registry keys. Your personal documents, including all .pptx and .ppt files, will remain completely untouched and safe on your hard drive.
How do I unhide the left pane if I accidentally dragged it closed?
Move your mouse cursor all the way to the left edge of your PowerPoint workspace. When the standard mouse pointer turns into a vertical line with two arrows pointing left and right, click and drag your mouse to the right to reveal the thumbnail pane again.
