POP accounts only download the Inbox, so that is why you don't see other folders on C2 (yet). Other folders will be automatically created once you send a message, save a draft etc.

Thanks for the response. Unfortunately I did send out several messages, but no Sent folder was created!

Under Tools/Account Settings, what is the setting in Copies & Folders for 'When sending messages..'? Is 'Place a copy in' checked?

Further to my previous response. After your input I sent out an email. Lo and behold a new Folder appeared, Junk, not Sent.

More. You're right! Under Copies & Folders, Place a Copy in: Sent was NOT checked. Thank you so much for this input which solved this problem. You are so helpful here are two more questions. How is a Draft folder created? Where do the Folders under Local come from? I created one called Keepers where I store emails I want to retain by subject. But on C2 also showing are Trash and Outbox. In my old computer, C1, every folder showing under my Email address also appears.

When you are writing a message, the menu item File/Save as.../Draft saves the message for later editing; Drafts folder is created the first time you save a draft. Outbox is where messages are stored when you select File/Send Later instead of just Send; File/Send Unsent Messages sends messages in Outbox.

Local Folders are folders that exist only on that computer, so any Local Folders on C1 are only visible on C1, unless you manually transfer them to C2.

Synchronizing mail between multiple devices is much easier if the accounts are set up as IMAP.

Check Server Settings in Tools/Account Settings to see where deleted messages are stored.
