If a PowerPoint file opens as read-only, you may not be able to save changes to the original file. This can happen because the file is marked as read-only in Windows or because editing restrictions were turned on in PowerPoint.
Resolution
Try Method 1 first. If the file is still opening as read-only, continue to Method 2.
Method 1: Remove the Read-Only File Setting
Use this method if the file is marked as read-only in Windows.
1. Right-click the PowerPoint file, then select Properties.
2. On the General tab, find the Attributes section.
3. Clear the Read-only checkbox.
4. Select Apply, then select OK.
5. Reopen the file and confirm that you can edit and save changes.
Method 2: Turn Off Read-Only Mode in PowerPoint
Use this method if the presentation was set to always open as read-only from within PowerPoint.
1. Open the PowerPoint file.
2. Select File, then select Info.
3. Select Protect Presentation.
4. If Always Open Read-Only is selected, select it again to turn it off.
5. Save the file, close it, and reopen it to confirm the read-only setting has been removed.
