Mail not sorting folders alphabetically
I have just imported thousands of folders, I needed them sorted Alphabetically to find the duplicates etc.
I looked at the old thread Mail Not Sorting new Folders Added Alphbetically and it makes sense, but as I have painfully lost a lot of email in the past due to disabling or deleting an account I want to make sure I am not going to make another mistake.
My accounts were POP and IMAP and all the folders are stored "On My Mac" so if I disable and close then reopen and enable, as per instructions in the thread will I lose my email?
Please dont guess as I have NO backup of all this mail including software registrations etc.
Thanks :-)
