Mail folders not recognised
I have linked Thunderbird to my iCloud mail using Apple's straightforward app-specific password facility. Thunderbird recognises the basic folders (inbox etc...) and I can send / receive mails.
Thunderbird does not recognise the majority of iCloud's Mail Folder hierarchy so most of my mail 'history' going back 20 years is missing. It is still present if I view it on iCloud's web service.
Two random folders (each containing 30+ mails) are available through the Thunderbird client. The remaining 70-80 folders are not.
This is a very simple Thunderbird set up, single e-mail account, no messaging or anything else (no need, don't want).

Assuming this is IMAP, try this: - highlight account in left side bar, rightclick and select 'subscribe' and see if the folders are available.
First thing I tried, all folders are subscribed, nothing happens. Thunderbird even left open overnight to verify that this was not just slow replication.
