My laptop was destroyed yesterday. I have purchased a new one today. Both were/are Win 11 64bit. The current version of Thunderbird on my new laptop is 102.2.2, I don't know what version of Thunderbird I had on my old destroyed laptop. I have kept regular backups of my emails and folder structure using the Import/Export function within Thunderbird [i.e. Right Click on the email and Export to a specific location]. I do not see this option on my new laptop installation of Thunderbird so I am unable to import my old emails onto my new laptop. I have searched through the help database but can't find anything that is relevant to my problem. I really need help urgently as all my emails are "invisible" to me at this time.
