Syncing to iPhone Question

I followed the instructions given to set up sync2em with my iPhone under supported devices, but I must be doing something wrong, as it is not working. Here is what I did:

  1. Went to Mail, Contacts, Calendar New Account
    2)Selected Microsoft Exchange
    3)As email, put
    Added as username

It also asks for Server - What do I put there?
And should Use SSL be on or off?

I am very sorry but we decided to no longer support Sync2eM service due to lack of interest from the customers.
