Unable to turn on out of office reply OWA exchange 2010

Hi there,

I have an Exchange 2010 server stilling on a Windows 2012 box and unable to enable out of office assistant through OWA when logging in under full version on any internet browsers, but I am able to if I log in under the light version

This is the error I receive when logged in under full version trying to enable out of office

I have tried the following to resolve this Issue so far

• Installed Exchange 2010 SP1 Rollup 1
• Checked the virtual directories to make sure they have the correct permissions as per this article  "http://blogs.technet.com/b/exchange/archive/2010/09/23/3411146.aspx"
• Ran IISRESET from elevated command line

Any other suggestion?

Thanks
