How to reduce the size of Microsoft Outlook folder

Asalam-o-Alaikum Wa Rahmatullah

I am working with Microsoft Outlook 2003. Currently the sizes of folders are as;

Archive 359Mb

Outlook 1.04Gb

I want to know the tips to reduce the size of these folders. I have set AutoArchiving “Cut out items older than 8 Months” and run AutoArchivi after 5 days.
