A manager might have been able to log on to the user’s account, check files, and save important files to other folders, but if the user account has been deleted, encrypted files will be accessible only if the encryption is removed or if the files are moved to an exFAT, FAT, or FAT32 volume (where encryption isn’t supported)..
