Save the Presentation in the Modern .pptx Format
Older PowerPoint file formats do not support modern cloud-based features. Converting the file to the current format usually unlocks the button.
If your presentation was originally created in an older version of Office, it might be saved as a .ppt or .pps file. These legacy formats operate in Compatibility Mode, which restricts access to newer features like Rehearse with Coach.
With your presentation open in PowerPoint, click on the 'File' tab in the top-left corner and select 'Save As' from the left sidebar menu.
Click the dropdown menu under the file name input box and select 'PowerPoint Presentation (*.pptx)'.
Click 'Save'. Close the presentation and reopen the newly saved .pptx file, then check if the Start Rehearsing button is now active.
