Hi @OAlterescu, I hope that you are well!
Thanks for reaching out to the Community!
You’d like to see the reply to the email in the portal, is that right?
I’d like to share the solution from @Lucila-Andimol on that post “Following conversation on customer portal” that might help you!
I’d like to invite a couple of subject matter experts to this conversation @Shadab_Khan, @FCorbaci and @Lucila-Andimol, do you have suggestions to share with @OAlterescu, please?
If anybody else has anything to add and/or share, please feel free to join in the conversation 
Thanks and have a lovely day!
Best,
Bérangère
