Email Threading : Email Objects has date 31.12.9999

Hi folks,

We have enabled Email threading in our project, and as a result now emails are getting linked to the transaction 'Service Request'.

But all these emails that I can see has 31.12.9999 as due date.(Due date not defined on mouse hover ).

We have both the inbound and outbound email objects present there.

Can you guys please help me in getting rid of the dates or how can we infuence these dates?

Regards,
