How can I delete a message from Outlook inbox without opening it?

In thunderbird I could right click on an unopened message and delete it from
a drop down menu. However right or left clicking on a message in Outlook
opens the message. Can I delete a message without opening it?

Don't use the Preview Pane. Configure Outlook to NOT use the Preview
Pane. That way when you select an item (which is also performed when
using the context menu so you can actually look at the context menu for
THAT item), Outlook won't try to show a preview of the item. You can
use the AutoPreview mode which show the first few lines in plain-text of
each item if you want to see some of the message before opening it.
