Exchange 2010 - allow authenticated (non admin) user to spoof addresses
I am trying to setup an mail enabled account that will let some specific programs email out using the clients 2010 Exchange server
Users in different offices use the application (locally) which generates automated reports. It can authenticate with the server - however they like to use their email addresses as the return address. I had created an account to be used across the company, but it fails to work. However if I use an account with admin rights it works fine.
Clearly I don't want to use an admin account for security reason
I could use the return email address account to authenticate - but since another company is involved in setting them up - I don't want them to have everyone's account/password that uses it. They should only have the details for an account without domain user permissions.
I have been looking at Extended rights - but can't see anything appropriate there.
