We are at the moment using Exchange 2003 SP2.
We have an application (App1 on Server1) that uses WebDav (through ASP.Net) within a Windows service to connect to Exchange and
a) Send emails from specific mailboxes
b) Interogate messages, extract the attachment and move the mail to a Success or Error based on some business rules. This is set on a configuration polling value for example 1 minute so the Inbox is polled every minute to check for new messages
c) Note all connections are made using the windows service $ account (eg $app1) using windows authentication from the application server.
Does anyone know if/how this will work with Exchange 2007? We will test in a lab first, but I was looking for any ideas/pointers? At the moment, the application points directly to the Exchange server that the mailboxes are located on, but I assume we will have to reconfigure to point to the CAS?
