Can you elaborate further on what you mean by chain body?

Do you mean the body of the email itself?

I tested email forwarding from ActiveSync (iOS) and the email forwards perfectly, and can be seen in my sent folder. What client are you using?

Hi,

Thanks for your mail.

lets suppose, when i do reply all to the users and do mail to the users they are receiving mail but, the previous chain mail is not showing.

Thanks,
