@oztech , I had Just setup exchange 2010 1 month ago in hosting mode with website panel . If you have installed exchange with the command setup.com /m:install /r:M,C,H,T /OrganizationName:TestORG /Hosting , then the exchange installation is perfect otherwise Iam afraid you have to install exchange again .
Anyways I can install exchange for you and configure website panel for exchange hosting . My email address is firstname.lastname@example.org
I've recently done a multi-tenant WebsitePanel install for both Exchange 2010 SP1 w/hosting mode and Exchange 2010 SP2 on-premises.
Contrary to post #5, you do NOT want /hosting mode as it will no longer be supported after Exchange 2010. Migration in the future will need to be a cross-forest migration - http://blogs.technet.com/b/exchange/...ting-mode.aspx. Not to mention all of the features you lose.
