By restricting permission, you will be able to allow specific users to access your PowerPoint presentation.
The first step is to click on the “File” tab to enter the backend view of your PowerPoint presentation.
Now, click on the “Info” tab from the options in the left part of your screen.
The next step is to select the “Restrict Access” option from the drop-down menu of the “Protect Presentation” option. It is the 3rd option in the drop-down menu.
From the pop-up window, click on the “Restrict permission to this presentation” checkbox. It is located at the top of the pop-up window.
In the final step, all you have to do is type in the email addresses of the users with whom you want to share the presentation, in the “Read” option.
