Thanks for your reply. I carried out step 1 previously when you replied.
I have noticed however that there are no email folders in the V5 folder for some of my email addresses. Why would this be?
And what are all those folders with long folder names with various letters and numbers?
Also, I don't understand why I had to copy all the emails (from all my email accounts) to my desktop and then import them back again into the Mail app? What is the point of this?
Some of your instructions are hard for me to follow.
I just want a record of all my past emails (sent and received) from my Yahoo email address and which will not change once I delete my yahoo account. I then just want them to sit on my computer until, perhaps, I want to read them at some point in future, or forward them to someone. I just want a permanent record of each of my past sent/received emails - that is all.
I am not ready to delete my yahoo account because I need to notify all of my contacts first.
But I still don't understand what all of these steps have done.
I see a new folder created in the Mail app (in the area On My Mac) called "Import-2", but I don't know what all the folders are that it has created. In addition, these folders only reflect some of my email addresses and also, it has not copied the current state of each email address. And I don't want the emails in my Mail app either - perhaps you did not understand this?
To be frank, its all quite a mess what has now resulted.
