The first one says “Enable conversations. ” This means that when you are viewing your message lists, you can also carry on conversations. The second box says “Show snippets,” which means that you will see a small snippet of the e-mail before you click on it. You can adjust either one of these settings by checking or unchecking the box just by clicking on it.

The first one, “Tabs,” means you can cycle between all e-mails that you have opened at one time. “Recent” means you can open up a drop-down menu and select one of the e-mails you viewed recently.

The default is set to “None. ” If you click on it, you will have 3 options: “None,” “Preview pane on the bottom,” and “Preview pane on the right. " You can choose a new one by clicking on the one you want from the drop-down menu.

There are 3 options to choose from: “Slim,” “Regular,” and “Relaxed. ” You can choose which one you want to use by clicking on the drop-down list and picking the one you would like to use.

There are 4 options to choose from: “Immediately,” “In 2 seconds,” “In 5 seconds,” or “Never. ” Choosing is just like the other drop-down menus; you click on it and when the list appears, click the one you want.

This is also a drop-down menu and has two options: “Show next e-mail” and “Go back to original folder. ”
