I was trying to install the BlackBerry Manager on my Exchange Server (Server 2003 x64) and Exchange2007. This caused my OWA to stop working so I followed the normal process of removing the OWA with the shell commandlet of Remove-OwaVirtualDirectory "owa (default web site)" - then I tried to create a new one with New-OwaVirtualDirectory -name "owa" -OwaVersion Exchange2007 -WebSiteName "Default Web Site" but I get the following error: New-OwaVirtualDirectory : An error occurred while creating the IIS virtual directory 'IIS://Exchange.Domain.ORG/W3SVC/1/ROOT/owa' on 'EXCHANGE'. At line:1 char:24 + New-OwaVirtualDirectory <<<< -name "owa" -OwaVersion Exchange2007 -WebSiteName "Default Web Site". I have rebooted and removed the .NET 1.1 and the Microsoft Exchange Server MAPI Client and Collaboration Data Objects 1.2.1 that the BlackBerry software had me install. I am out of ideas. Anyone got any ideas?
