I am using Mac outlook! Originally i planned to export one email folder to my external hard disk. Accidentally, all my emails were exported to an olm file but corrupted afterwards! I could neither import back my emails nor repair the olm file. Anyone can help how i can 1/ repair the olm file; 2/ or restore my previous setting; 3/ reimport the previous emails; 4/ or any other ways to solve!!!!!!!!

It seems that it is a common error that olm file is easy to corrupt as i can find many paid softer to rescue it!
