Pretty simple, right? Now, let’s take a look at creating your own custom search folders, which are way more powerful. Just click the search folder you want to create, and then hit the “OK” button. It’s a super handy search folder to have around because it shows all your unread mail, no matter what folder it’s stored in. Here, we’re creating a new search folder that shows unread mail. Most of the folders are pretty self-explanatory, so we won’t cover them in detail-you can just browse through them. You’ll see a bunch of predefined search folders organized into categories like Reading Mail, Mail From People And Lists, and Organizing Mail.
To create a search folder, switch to the “Folder” tab on the Ribbon, and then click the “New Search Folder” button.
You won’t be able to even select that “Search Folders” folder, though, until you’ve created your first search folder.
