While there are multiple users who can view and edit a presentation, there can be only one Owner per presentation. Transfer Ownership allows you to transfer ownership of a presentation from one user to another. Only the current owner of the presentation can make this change.
Step 1: To begin, open the presentation that you want to change ownership of.
Step 2: Add User 2 as a collaborator to the presentation you would like to transfer.
Step 3: In the Collaborate section, under "Who Has Access", click the drop-down arrow and select Make Owner.
