Outlook Webparts not available in list of webparts

Another thing that is very basic today. 
I needed to drop the OWA webparts on a page and to my surprise they were not listed in the list of wepbart in my 2010 Publishing site.

Activate the “Sharepoint Server Standard site features” will do the job.

Voila !
