Q: Cannot Set Default Mail App in El Capitan
I was using Outlook 2016 before upgrading to El Capitan. After the upgrade I decided to switch to the default Mail app. Unfortunately, when I try to make the switch in Mail > Preferences, the app I choose does not stick. When clicking a link, closing and restarting Mail, or even waiting just a few minutes, the default Mail app switches automatically back to Outlook 2016. Any thoughts?
I am running a mid-2011 Macbook Air.
MacBook Air (11-inch Mid 2011), OS X El Capitan (10.11)

I don't use Office, but knowing Microsoft, it may be forcing you to use Outlook as your default email reader. If so, you'll either have to get rid of it or refer to Microsoft for support. Before doing that, see below.
Although the problem is not the same, please follow the instructions in this support article to reset the Launch Services database. If you don't already have a current backup, back up all data before proceeding. You may have to log out or restart to see a change.
