Use Launchpad to delete an app

Emails deleted in Outlook reappear in inbox over and over. I use godaddy as my email host and then I set-up outlook as my email interface (IMAP) and the data files are in.pst. When I delete emails from outlook, they appear again. On a slower Mac on which Safari has visited any reasonable number of sites, I expect it may take a lot longer to fill in the list and to update when Remove is clicked. Click next to the app that you want to delete, then click Delete to confirm. The app is deleted immediately. Apps that don't show either didn't come from the App Store or are required by your Mac. To delete an app that didn't come from the App Store, use the Finder instead.
