I changed the provider for my domains and since there is no possibility to put an IMAP account into an inactive/completely offline state, I wanted to copy all mails of my old account to a local folder, so I don't get any error messages because the server can't be found, but it doesn't work. Marking all mails in a folder with ctrl + a works, opening the menu with right click works, but when I click on the options to copy or to move the mails into the local folder, nearly nothing happens. There are a handful of mails in the designated local folder, but the very majority stay where they are and don't get copied as well. I could try to copy or move the mails one by one, but since there are over 19k mails in my inbox, I definitely won't do that. I'm using Thunderbird 128.8.1esr. Can anybody help me?
