Some things you do in Outlook ask for confirmation. For example, the first time you try to Dismiss All on a list of reminders, Outlook asks you if you're sure you want to do that. If you don't choose an option on that dialog box, Outlook won't let you do anything else. Check for open dialog boxes.

If you try to delete or move a large number of messages at once, Outlook can appear to hang, but really, it's working behind the scenes. Check the status bar at the bottom of the screen. If Outlook is performing some operation on hundreds or thousands of messages at once, it might appear to be stuck. Give Outlook a few minutes to finish the process and it should start to work again.
