You can easily save emails as .EML file. just open Outlook select what all emails you want to SAVE and SHARE with your attorney. Right Click and select "COPY" option and then create a FOLDER and in that folder, right click and select PASTE option. You will get all those emails as files with extension msg which can be opened anywhere with a OUTLOOK client.
Hope this helps.
Please let me know if you have any further queries.
If you need, I can do a quick remote session and show you how to do the same. Please let me know.
