Microsoft PowerPoint for Mac: Smarter Keep Source Formatting slide pasting experience

MC1492155 · published Oct 8, 2026 · 0 comments

PowerPoint for Mac now imports only necessary slide masters and layouts when pasting slides with Keep Source Formatting, reducing file size and improving performance and collaboration. Users can revert to the old behavior via settings. Rollout began late September 2026, completing by late October 2026. No action required.
