It is really difficult to work out any email order in this system. Is there any chance that you build something similar to Outlook or any other email program?
I loose completely track when I am in our business account. When I open the conversation, i see first emails from 3 month ago. Then I try to find the newest version but I am not even successfull.
As the email is not an SMTP account, I can not connect it to a better email service to read relevant emails.
I am sure you can do better :-)
