- Scenario
- Multiple users are co-authoring and editing a presentation simultaneously.

Understanding Undo Behavior in PowerPoint Co-authoring
The Undo command operates on a per-user basis to prevent accidental deletion of a collaborator's work.
In both PowerPoint desktop and PowerPoint for the web, the Undo command exclusively reverses your own recent changes. It is designed this way so that you do not accidentally undo the hard work of your collaborators.
Note that if another user makes an edit to the presentation after you have undone your changes, the Undo command may temporarily become unavailable.
Make your desired text or design changes on the current PowerPoint slide.
If you make a mistake, click the Undo arrow in the Quick Access Toolbar or press Ctrl+Z. This will only revert your local change.
Wait for the changes to sync. Your collaborators' ongoing edits will remain unaffected by your undo action.

Frequently Asked Questions
Can I see version history if Undo is no longer available?
Yes, if the presentation is saved on a cloud service like OneDrive or SharePoint, you can access Version History to view or restore previous versions of the file even if the Undo command is grayed out.
What happens if two people edit the exact same text box at the same time?
Usually, the system locks the specific object being edited by one user. If simultaneous edits do occur, the application merges the changes or prompts you to resolve any conflicting edits.
Does the Redo function work the same way as Undo during collaboration?
Yes, just like Undo, the Redo command only reapplies the actions that you have personally undone, without affecting the changes made by other authors in the presentation.
