Is there a way to secure a powerpoint presentation against edits?
Three options I can think of:
- Under the Office menu|Prepare, you can select Mark as Final, which restricts editing. Note that this is not security based as any user can turn it off, but it's a reasonable indicator. http://office.microsoft.com/en-us/powerpoint-help/prevent-changes-to-a-final-version-of-a-document-HA010132569.aspx.
You could set a Modify password under Tools|General Options on the Save As... dialogue.
You could save as another format such as PDF or XPS as RichardM suggests.
Why not save the presentation as a PDF? Some formatting may not work out perfectly, but links will still work and it will not be editable as a PowerPoint file.
