OWA Not Loading Correctly - Exchange 2007

If Exchange OWA is not loading correctly (without graphics, looks very basic) you need to follow the below steps to get it up and working.

1. Load the Exchange Management Shell
2. Navigate to your Exchange Bin directory via the management shell - usually C:\Program Files\Microsoft\Exchange Server\Bin
3. Run the UpdateOWA.ps1 script (done by entering .\UpdateOWA.ps1)
