Hold down the Ctrl key (for a _copy_ operation) and use the mouse to drag a folder from the IMAP account to e.g. "Local Folders". That creates a copy of the entire tree, messages are downloaded etc.
I have just now (to double check) copied "ml-admin", a subfolder under my Inbox on my opensuse.org IMAP account, with two more levels of subfolders, and some 3000 messages in total. Took a little more than 30 seconds.
Ok, I tried that operation and it worked (I was surprised), although leaving Thunderbird busy and not responsive for several minutes. But that is not the operation I need to do.
You said "namely how to download email to local machine at some point in time", which is what this copy operation does.
Typically I would select a bunch of old mails in the INBOX and try to drag them to another folder, typically a folder under my local dovecot server. I tried that a week ago and failed. I try now, and it fails, does nothing. The block can be dragged, but on mouse release the blue block goes back to INBOX. Same if destination is on "local folders".
I have just moved 7 files from one subfolder to another under the same IMAP account, worked just fine. Even Ctrl-Z to undo worked fine. Then I moved them into a subfolder under "Local Folders", also worked just fine. Also Ctrl-Z. All on our hosting dovecot server - I don't have access to another one to try a server-to-server.
It is select messages in one folder, right click, move to, select destination folder. One by one.
See above. If necessary I'll be happy to make a video? I made a couple of screenshots, see attached.
Well, see above, what I move are the old messages from the folder. Typically those older than two months. Not the entire folder. And I do it using Alpine because it runs faster, and makes marking messages with criteria easier.
Maybe Alpine is buggy or functionally incomplete? -- Per Jessen, Zürich (2.1°C)
