To specify Microsoft Outlook 97 as the program you want to open MailTo URL addresses, use the following steps.
Internet Explorer 4.0, 4.01, 5 for Windows 95/98 and Windows NT 4.0
In My Computer, click Options (or Folder Options) on the View menu, and then click File Types.
Click the URL:MailToProtocol line to select it, click Edit, click Open in the Actions box, and then click Edit. Click the Application Used To Perform Action box and press DELETE to delete the data in the box.
Type the following single line for the Application Used To Perform Action box for the Open command:
C:\Program Files\Microsoft Office\Office\OUTLOOK.EXE" -c IPM.Note /m "%1
NOTE: Type the quotation marks in the box.
To save the changes, click OK until you return to My Computer.

Geen idee welke versie van Outlook je hebt, maar ik zou denken dat bovenstaande voor alle versies geldt (maar ik ben geen expert ). Succes ermee.
