Where Is Your Postbox Profile Located?
Postbox profile folder with mail, accounts and settings on Windows and macOS.
Last updated
Postbox inherits the Thunderbird-style profile system: one folder holds mail stores, account settings and preferences. Profiles.ini maps names to paths.
Local folders and archives live inside the profile. Copy it whole rather than picking files.

How do I move Postbox to a new computer?
Copy the whole profile folder with Postbox closed. Accounts, local folders and settings travel together. Passwords may need re-entering on the new machine.
