restoring deleted mail
Hundreds of emails were accidentally deleted from my computer and I am having difficult restoring them. They all appear in a Time Machine Backup and I retired this IMAP folder to the desktop. I can see the individual files in this desktop folder but copying individual files over to my the equivalent folders in my Libray does not make the files appear in the Mail app. I have restarted and rebuilt preferences - is there something else I need to do? Thanks
