MS Access 2.0 to MS Outlook 2003 Email

Our Time & Attendance System (TAS2000), developed in MS Access 2.0 sends certain notifications by email, through default email client (Eudora, Outlook etc). We have suddenly hit a road block where the client is using Outlook 2003. A message comes “can’t open a mail session”. So we had to install free version of Eudora to use this email facility in TAS2000 as the department managers wanted to use this feature. I have tested with Outlook 2000 SR-1; but understand (searched Internet) that MS has put some blocks from Outlook 2000 SR-2 onwards to prevent virus spreading. However, I would like to know if there is a way we can send email using our existing MS Access 2.0 based TAS2000 with OUTLOOK 2003.
