Moving select subfolders to a new thunderbird client on a new computer

Hey there! Moving specific subfolders to a new Thunderbird setup is totally doable. First, make sure you've got Thunderbird installed on your new laptop. Then, in your old Thunderbird, right-click on the subfolders you want to move and choose "Copy To" from the menu. Pick your new Thunderbird account as the destination. The emails will be copied over. If you're using IMAP, they'll sync automatically. If you're on POP, just make sure to also back up those folders before deleting them from your old setup. Hope this helps you get your subfolders set up on your new laptop! If you run into any bumps, don't hesitate to ask.

Howdy - I have Thunderbird set up and running on my new laptop. It was created with the profile from my old laptop. I have an even older laptop that has some folders (and content) that I need to keep by moving them to my new set up - I am just not sure how to accomplish that with these instructions.

If the account is IMAP, just subscribe to the folders on the laptop. If the account was POP on the old computer, open the profile folder (Help/Troubleshooting Info, Profile Folder, Show In Finder (Win: Open Folder)), close TB, open the Mail/<popservername> subfolder, look for the mbox files with no extension, named after folders, and copy them to the Mail/Local Folders location of the profile on the laptop, with TB closed. Restart TB and find the folders under Local Folders in the Folder Pane.
