How can I recover everything after restore?

Hi! I use the restore command and then it seems like my account is then deleted. Now my eM Client is empty. How can I restore everything?

Add the account again in eM Client, and if you were using IMAP the folders and emails should reappear after the first sync.

Thanks. I added the account now. But is there any way to recover all the mails before the restore?

Your restore will only be as good as your backup. So if your backup did not contain your old emails, there is no way restore would be able to restore them.
