when using Gmail imap, how remove existing Personal Folders that came as default with Outlook 2007/2003?

I found that annoying when you open outlook It’s open up inbox in personal folders in outlook than open up the imap inbox. You can’t remove the personal folders on outlook when using imap as Imap don’t have ability to store calendar, task data. I have found a work around though 

On outlook  tools >options >other tabs >advanced option  Capture

Click the browse button and select the inbox from the imap folder works like a charm
