Windows 8 is still very new, and flashy, and somewhat annoying (even with the Windows 8.1 Update!) with some of its quirks! Recently, I installed Microsoft Office 2013 on my new laptop, and ran into an issue where clicking on email addresses open the native Mail app instead of Outlook. If you're having the same issue...here's how to fix it!
Step 1: Open the Default Programs control panel application (you can find it by using Search)
Step 2: Click "Set your default programs"
Step 3: Select "Outlook (Desktop)" from the list, then click "Choose defaults for this program"
Step 4: Click the checkbox next to "MAILTO" and hit "OK"
Your Outlook should now be the default when clicking links!
