Prospect doesn't allow email chain respond to emails (which is normal practice and you lose context if you don't add the previous email).
This means its high labor for the sales team to go back and forth between their outlook and prospect.
We use a shared inbox so our prospect crm add-in doesn't work. Even if it did, it still doesn't work great as can't create opportunities etc from there or continue with email chains (I could move the sales to it's own account)
I should pobably add - ultimately, we want to use template emails inline with the email that was sent to us.
Right now, if we respond from prospect, it doesn't have the previous email or we have to copy/paste over - it's a hassle and a hassle for those receiving the emails too.
