The outliers are so far away that it forces the box plot to be squished as the range of data is so large, you could use outlier detection techniques to help with this.

Using a log(y) will help by reducing the amplitude of the outliers and the spread of values and make the box plot more easily visible.

You can also click the zoom button above the plot in Rstudio if you are using that as your IDE, this will open the plot in a new window that can be fullscreen.

Hope this answers your question.
