A family of Microsoft presentation graphics products that offer tools for creating presentations and adding graphic effects like multimedia objects and special effects with text.
PowerPoint files can fall out of sync if the local Office cache is stuck, if the deck is very large, or if two computers keep slightly different cached copies of the same presentation.
Besides the solutions provided by the Q&A Assist, here are some suggestions you can try:
First, make a backup copy of the presentation somewhere safe. Then close PowerPoint on all computers. On the computer that is not syncing correctly, clear the Office Document Cache, since a damaged cache can keep old PowerPoint changes from uploading properly.
It is also recommended that you check whether the presentation is very large, especially if it contains videos, high-resolution images, audio, or many slides. If it is a big file, try compressing media in PowerPoint or splitting the deck into smaller presentations, then test syncing again.
Also check OneDrive’s Version History from the browser to confirm which copy has the latest changes before editing again.
