Avoid using pst file

Hello !!

I installed DAMO 7.0.2 on Outlook XP and 2003, everything looks likes is going fine but I got a problem, the users are importing their old pst to the new DAMO profile and those mails are being replicated to their Domino´s nsf.

Is there a way to stop replicating old mails.

I hope someone can help me.

Thansk a lot.
