If you installed Thunderbird (at home) and you can not see the folders you created in your mailbox, you should do the following:
Go to Tools >Account Settings >Server Settings >Advanced >remove tick at the "show only subscribed folders' box.
If you still don't see all your folders:
Go to the folderpane (on the lefthand side) and right-click the account of which you can not see all the folders. Select 'subscribe' in the right-click menu and select the folders you want to display in Thunderbird. You may have to close and restart Thunderbird to then see all the folders.
