Email dashboard snapshot function: Why is the Grid KPI not appearing accurately in outlook inbox?

Email dashboard snapshot function: Why is the Grid KPI not appearing accurately in outlook inbox?

This Issue occurs if the email client used is Outlook 2007. In Outlook 2003, it does work fine. This is to do with the additional security settings in MS Office 2007. We donot validate which outlook version the end users use to validate the rendering of the dashboard content over email.
