"Changed servers"? Can you elucidate?

Thunderbird will create such folders as and when they are needed.

However if you expect data that has previously been shown in these folders to be visible, you need to understand the differences between POP and IMAP and recognize that mail is stored in different places.

Messages stored on your computer will remain visible (POP or in Local Folders). Messages stored on other computers (IMAP servers) will only remain visible if you remain in contact with those servers. If you tweak an account's settings to use a different server, it loses contact with the original server and so you lose sight of the messages stored on it. Messages stored on a server in folders other than Inbox will be invisible to you if you connect to it using POP.

So, was it POP or IMAP? Is is POP or IMAP now? What did you change?

Hi

It's on IMAP and I've just changed my website and email hosting account and so was no longer receiving my emails via Thunderbird so deleted the previous one and reloaded and it installed automatically.

I'm not particularly techy and it's always worked before!

As it is IMAP you need to subscribe to see those folders.

then make sure you can see all the folders. View > Folders > All

You should also check your settings:

• Tools > Account Settings > Copies & Folders

• select 'Place a copy in'
• select: 'other' and choose Sent on mail account

For Archives, Drafts, Templates,

• select 'Other and the respective folder on the mail account'

• Click on OK to save changes.

Note; if you did not get a copy of the emails off the old server into your Local Folders and you move away from the old server to a new server, you will not have any access to those emails on the old server.

Thank you!

I followed your advice and it worked so now solved.

I had already saved the emails from my old server as I was aware that I wouldn't have access to them.
