How to Uninstall Postbox

To Uninstall the Postbox Application:

macOS

  1. Within Apple Mail, select Preferences > General. Select Apple Mail as your default mail reader.

    WARNING: THIS ACTION CANNOT BE UNDONE!

    (Note: In macOS the user Library folder is hidden. To access it, go to the Finder, and hold the Option key (for 10.11 and below) or the Shift key (for 10.12 and higher) while clicking on the Go menu at the top of the screen. Library will be one of the options.)

Windows

If the Uninstall Wizard does not run, you can start it manually, by running C:\Program Files\Postbox\uninstall\helper.exe.
