I had a problem with OWA it was either coming up with a blank page. I reinstalled IIS but now when I go into the Exchange Management Console, Server Configuration, Client Access. Nothing is listed under the Outlook Web Access tab. FYI The platform is Exchange 2007 on a Windows Server 2003 box.I tried disabling Outlook Anywhere and reenabling it and I get a warning (see below) and OWA still doesn't work.Any ideas?--------------------------------------------------------Microsoft Exchange Warning--------------------------------------------------------The following warning(s) were reported while loading topology information: Get-OabVirtualDirectoryCompleted Warning:The offline address book (OAB) virtual directory "OAB (Default Web Site)" exists in Active Directory, but not the IIS metabase. Please recreate the OAB virtual directory. --------------------------------------------------------OK--------------------------------------------------------

Hi, Whether you have attempted following KB to reinstall IIS and Exchange server? I would like to explain if you have to reinstall IIS on a computer that running Exchange Server 2007, you must also reinstall Exchange 2007. This is to restore links to IIS that provide Outlook Web Access functionality together with other Exchange-related Web services such as the Availability service. How to remove and to reinstall IIS on a computer that is running Exchange Server http://support.microsoft.com/kb/320202/en-us Mike

There is no way to restore these links without reinstalling Exchange?I would prefer not to reinstall exchange.

Hi, According to previous KB, we have to reinstall Exchange Server (Client access Server role) if you reinstalled IIS components. In addition, I would like to explain that reinstall Exchange Server is able to help clear other potential issues. Mike

Hi,Please let me know whether you have any further question regarding the problem.Mike
