I had an email account on first hosting server with its IMAP and SMTP. The server has been cracked and now I couldn't read emails from it.
I moved my doamin to another hosting server with another IMAP and SMTP. Now all my old messages kept on first-server, where I cann't access, and all new messages on the second-server. Also all my old messages kept in Thunderbid.
Now I change IMAP and SMTP server in Thunderbird and lost my old messages, but get new.
How to prevent old messages lost and get new messages in Thunderbird?
Unless you configured Thunderbird to actually download the emails, then you don't have a local copy of the emails, so there is nothing you can do to "keep" them since they are only contained on the server. – Ramhound – 2015-11-12T19:10:53.387
Now Thunderbird.contains old messages. I want to keep them, configure Thunderbird to new email settings to receive new messages, and want to add old messages to new ones. Merge them. Is it possible? – Ivan Z – 2015-11-12T19:17:35.587
As I indicated unless you configured Thunderbird already to actually download the email, then its very likely, the emails ONLY exist on the server. – Ramhound – 2015-11-12T19:24:41.370
Lets try again. (1) Both Thunderbird and server (old server where I coudn't login) keep messages. I want to keep them. (2) Also I want to continue to get messages to the same email. That new messages will be stored in the new server and in Thunderbird. (3) If I configure T. to get messages from new server, old messages will be deleted. (I try, I know). (4) I don't want that T. will delete old messages. I want that T. will merge them with new. How to do this? – Ivan Z – 2015-11-12T19:37:57.117
