Exchange 2010 – Blank OWA Page?

KB ID 0000429

Problem

When trying to access Outlook Web App (or Outlook Web Access for those used to earlier versions of Exchange), you see a blank white page and nothing else.

The certificate and IIS works but no OWA.

Solution

This is usually due to an exchange pre-requisite that is missing, or one of them is not working.

1. Launch the Exchange Management Shell, (Start > All Programs > Microsoft Exchange Server 2010 > Exchange Management Shell).

2. Issue the following command.

[box]Import-Module ServerManager[/box]

3. Issue the following command.

[box]Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy -Restart[/box]

4. Issue the following command.

[box]Set-Service NetTcpPortSharing -StartupType Automatic[/box]

5. Retry OWA.

Exchange 2010 Service Pack 3 Error – ‘The IIS 6 WMI Compatibility component is required’

KB ID 0000771 

Problem

If you attempt to install Exchange Service Pack 3 on an Exchange server that is currently running Service Pack 1 you will see this error.

Error:
The ‘IIS 6 WMI Compatibility’ component is required. Install the component via Server Manager.

Solution

Note: This was a prerequisite for SP2, so if you do not see this error your Exchange was deployed with SP2 slipstreamed into it, or the problem was dealt with when SP2 was installed.

1. Launch the Exchange Management Shell
