Question : Can I combine Outlook Express and Microsoft Office Outlook?

I've always used Outlook Express and know it well.  Than I purchased Microsoft Office 07 and it has Microsoft Office Outlook.  Is there a way to use only Outlook Express as my default as I'm not that familier with Office Outlook.
