Question details

Users encounter a deprecated-feature error message when trying to insert or reuse slides from an external presentation file.

Product: Microsoft PowerPoint
Device & OS: not provided
Scenario: Attempting to merge or insert slides from a different, often older, presentation into a current presentation file.
Observed behavior: PowerPoint interrupts the insertion process and displays a "This Feature Is Deprecated" error message instead of adding the slides.

Before you start

Ensure you have access to a current desktop version of Microsoft Office and that both your source and destination presentation files are saved locally on your computer.

Solution 1Recommended

Use Modern Slide Reuse Features or Copy and Paste

The easiest way to bypass legacy workflow errors is to use the built-in modern "Reuse Slides" function or directly copy and paste the slides.

Older methods of importing slides may trigger deprecation warnings in current versions of PowerPoint. Using the supported native tools ensures a smooth transfer of your content.

Open Both Presentations

Launch a current desktop version of PowerPoint and open both the source presentation (the one containing the slides you want) and the destination presentation.

Use the Reuse Slides Tool

In the destination presentation, navigate to the 'Home' tab on the ribbon, click the 'New Slide' dropdown, and select 'Reuse Slides'. Use the side panel to browse for your source file and insert the slides.

Alternative: Direct Copy and Paste

If the Reuse Slides tool fails, go to the thumbnail pane on the left side of your source presentation. Highlight the slides you need, press Ctrl+C to copy them, switch to your destination presentation window, and press Ctrl+V to paste them into place.

Preserve Formatting: When pasting slides, you can click the small 'Paste Options' icon that appears and select 'Keep Source Formatting' to ensure your slides look exactly as they did in the original file.

Solution 2

Update the File Format and Microsoft Office

Older presentation formats (.ppt) can trigger compatibility and deprecation errors. Converting the file and updating Office resolves format-specific warnings.

Frequently Asked Questions

What does the "This Feature Is Deprecated" error mean in PowerPoint?

This error indicates that a specific tool, legacy workflow, or outdated file format you are trying to use has been phased out by Microsoft and is no longer supported in the current version of PowerPoint.

How can I insert slides from another presentation without triggering this error?

You can safely import slides by using the modern "Reuse Slides" panel found under the Home tab > New Slide, or by simply opening both presentations and using the standard Copy (Ctrl+C) and Paste (Ctrl+V) commands.

Will saving an older .ppt file as a .pptx file fix slide insertion errors?

Yes. Converting older .ppt files to the modern .pptx format updates the underlying file structure, ensuring full compatibility with current PowerPoint features and often resolving deprecated feature warnings.

Does this issue happen if my Office application is outdated?

It can. Sometimes, a mismatch between file features and your specific PowerPoint build causes unusual errors. Updating Microsoft Office via File > Account > Update Options often resolves unexpected deprecation messages.
