How to avoid the Mail metro app from emailing a link from a CRM record?

Hi,

I am running Windows 8 and Office 2013 with CRM 2011. All is well until I emailed a link from within a record i.e a service case or contact. Instead of opening my standard Outlook it CRM asked me if it would allow the mail app to send the link.

Is there a way to switch this back to using standard Outlook as I do not wish (at this moment) to sync my Outlook with the mail app.

thanks
