I want to add an item to the right-click menu in Outlook Web App in Exchange 2010, so that when the user click in OWA on my created custom menu item , it will go to the new URL (my application) with the properties: ae, a, etc.

I followed the steps mentioned in and the replies from

Simply, I just modified the 'UIExtensions.xml' in '\forms\Customization'.
Here is the Code Snippet:

<RightClickMenuExtensions>
     <RightClickMenuEntry 
       Icon="16x16.gif" 
       URL="https://google.com/" 
       filter="IPM.Foo;IPM.Bar">
       <string language="en-us" text="My Application"/>
     </RightClickMenuEntry> 
 </RightClickMenuExtensions>

after that, i reset the IIS. However, nothing changes

What I have tried:

i have
(1)copied and renamed the UIExtensions.xml.template to UIExtensions.xml in \forms\Customization folder.

(2)modified the xml file with the code mentioned above.

(3)copied a 16X16 pixels image file into the customization folder

(4)done an IISreset
