Why is the "Connect to Outlook" button is grayed out in SharePoint 2013?

The reason is because the Minimal Download Strategy feature does not download all the necessary scripts to enable the "Connect to Outlook" feature.

What is Minimal Download Strategy?
It is a new feature in SharePoint 2013 that improves client rendering performance and fluidity when navigating from page to page by download only the changes between two compatible pages.
Fewer bytes will be downloaded and the page will appear more quickly.

To enable the "Connect to Outlook" button, you can disable the Minimal Download Strategy, but this is not recommended as you will lose out more of the cool capabilities that it can perform.

The recommendations to get the "Connect to Outlook" button, just refresh the page by pressing the "F5" button or refresh on the browser, the button will be enabled.

    This doesn’t work for my site. I can see Connect to Outlook for Calendar and libraries but not list. What else could it be?

    Geri, try CTRL-F5 to force a reload. If that doesn’t work, turn off MDS just to test that it is indeed a missing .js file. If so, figure out what .js file is missing and then embed a script web part to force it to load. I have not tested this idea but
    it seems like it should work.
