Moving Postbox to a Different Computer


All Postbox settings and data are stored in a data folder that resides outside of the application. You can transfer your Postbox data folder from one machine to another by following these instructions:

  • Make sure that Postbox is installed on both the source and target machines. 
  • Quit or exit Postbox on both machines.
  • Next, move the Postbox data folder from the source machine to the corresponding location on the target machine.

The location of the Postbox data folder is as follows:

Postbox 5 and below: ~your home folder/Library/Application Support/Postbox
Postbox 6 and above: ~your home folder/Library/Application Support/PostboxApp

(Note: In macOS the Library folder is hidden. To access it, open the Finder, hold the Option key, then select Library from the Go menu.) 

Postbox 5 and below: Users\username\AppData\Roaming\Postbox
Postbox 6 and above: Users\username\AppData\Roaming\PostboxApp

(Note: The AppData folder is a hidden folder; to show it:

  • Windows Vista / 7 - Open a Windows Explorer window and choose "Organize → Folder and Search Options → Folder Options → View (tab) → Show hidden files and folders".
  • Windows 8 and higher: Open a Windows Explorer window and choose "View Tab → Options → View Tab → Show hidden files and folders, then click the Apply button".)
