Thank you.

Try checking the documentation at http://www.microsoft.com/technet/prodtechnol/exchange/E2k7Help/8812f27c-4532-46e9-8621-cf0255456808.mspx?mfr=true; it will probably explain the basics of what you need to do: get a certificate, install it with IIS, and set up IIS to use it.

Thank you for your Answered.. But Your articalone thing fromwhat i need. Ineed you to tell me the steps for installing the OWA from A to Z. ----------------- I am trying to read from internet and apply.

Thank you

1. The OWA server has to be in the same Active Directory forest as your other Exchange servers, so you can't put it in a workgroup (I think that's what you're asking).2. MS doesn't recommend using a separate DMZ for the front-end server.Instead of using a DMZ, you can put the front-end on your internal network and only publish the ports you want to give access to-- in this case, TCP port 443 will give you SSL access to the OWA server without openng any additional ports.

Thank you Very much
