I'm using Excel Office 2007. I would like a VBA code to create a task in
Outlook based on a date in an Excel workbook. Once the task is completed, I
would like that completion date entered into the Excel Workbook. Is this
possible?

My initial date is located in the workbook 'Loan Book', worksheet 'Loan
Data' cell CN9. I would like the task completion due date to be four days
prior to the sheet date. Once the task is completed, I would like that
completion date CP9.

Thanks in advance for any advice.
