We receive email from one address (let's say ticketsystemA@domain.com) with support tickets, we want those emails to be imported by our other ticket system.
The problem is that all tickets are send from the same user. So when we import, all tickets belong to ticketssystemA.
The first line of the body contains the emailadress of the real user that created the ticket, the rest of the body contains the ticket (and perhaps attachments).
We would like to autoforward the mail to ticketsystemB@domain.com with the sender adress being changed to the address found in the FIRST line of the email.
We have an on-prem Exchange 2016, the ticketsystemB is Always on the same domain as the real ticket creator.
Sorry for my bad English
