Hijacking 'Copy emails to Worksite' toolbar button in Mailsite

seeen

Hi,

I would like to be able to determine when a user has used the 'Copy emails to Worksite' from within Mailsite so that I can tag the selected emails as having been filed in their inbox(using selective formatting and outlook categories). I can access the button click event from the outlook object model, but this doesn't take into account whether the user has cancelled the operation within the worksite dialog. Is there another way to to get at it?

Thx

Sean
