You need Administrative or Edit Project Ownership permissions to perform this function.
1) On projects listing screen click on users name under USER filter. This will display all the projects for this user.
2) Do a CTRL+A on your keyboard, this is a hotkey that will highlight all projects even the ones beyond the length of the screen.
3) Do a right mouse click over the highlighted projects to display a menu and select "Change Project Owner".
4) A "Project Ownership" window will open and from the dropdown you will get a list of all users in your company that uses AutoQuotes. Select the new owner and click on SAVE button.
