For the past 2 months i've been living, learning,breathing, and sleeping with AD, Exchange, and IIS. I'm trying to accomplish what Ithought would bea simple task. Turns out it wasn't. I'm using Windows Server 2003 Enterprise, andExchange 2003 SP1. I do not want to use any 3 party solutions. I have two companies I want to hostemail forwww.CompanyA.comand www.CompanyB.com I do not want CompanyA to knowCompanyB existsin any way. I need OWA access forbothCompanyAandCompanyB employees. I'm here to get some fresh ideas and thoughts. I've pushed my way through these next two sites. I don't see where they address OWA. http://www.msexchange.org/tutorials/Shared_Hosting_Exchange_2003_Part1.html http://www.msexchange.org/tutorials/Shared-Hosting-Exchange-2003-Part2.html All ideas welcome, TIA!
