Hello, and welcome to the forum.
I don't believe you can export date data to Excel. But, I just discovered that importing Outlook data into Microsoft Access includes date data. Again, I just learned this, so I'm not completely familiar with some details of how to control, or if you have any control over, what gets imported.
Anyway, the procedure is to open Access, create a new/blank database, and then select File|Get External Data|Import, and select Outlook() in the Files of type box.
Once you get this data in to Access, it an easily be exported to Excel if you prefer working with Excel.
I'm working with Office 2003.
