I have two Folder-trees below my email-Folders. What
are the difference between this two Folder-trees? The Archive-Tree I understand, it will produced while archiving. But what with the local-folder tree. How can I delete the local Folder-tree? I would like to have my emails either in the standard email-folder or then archived.
You can first delete mails from the local folder (make sure you back them up if you don’t want to lose them) and then go to Tools>Settings>General and uncheck the “Show Local Folders” checkbox.
Local folders contain messages downloaded to your machine. That’s either done automatically when one uses POP3 where (normally) no copies are kept on the server and no other folder than INBOX is provided. Or you use them for local storage of messages you do not want to keep on the server (archiving, privacy, running out of space …).
