OWA is not loading

All of sudden OWA is not loading in my Server and it is throwing error " Unable to initialize outlook access ". This started after applying MS updates.

Using Exchange Shell command line

Get-OwaVirtualDirectory

 will display a list of all the Exchange Virtual Directories on that server. The one you are looking for here is "OWA (Default Web Site)" on a default install.

To remove OWA from IIS

Remove-OwaVirtualDirectory -identity "owa (Default Web Site)"

TO Recreate OWA execute below command.
New-OWAVirtualDirectory -OWAVersion "Exchange2007" -Name "owa (Default Web Site)"

me also confused how to do this ????

Are you using MS-Exchange 2007 Mail server along with HC panel ?
