Hello Saravanan,You can think of implementing SMTP domain namespace sharing which should work for you. A good starter reading is available athttp://support.microsoft.com/default.aspx/kb/321721. But you need to keep in mind that the implementation in your branch office will be completely different than your current organization. VPN is recommended for the security purposes and to prevent the mail looping while routing. Even using SMTP domain Names Space Sharing if you forward the messages to another system and the destination system uses a public IP (not using VPN) the mail looping will cause routing issues. In short, I dont see any other way to skip the VPN configuration.-Milind Naphade
