Thanx for the reply Tom,
My requirement is that I have to place(embed) the object (outlook draft
or mail) in a particular cell as the every cell belongs to a particular
person with particular date and I want to embed the outlook object for
this person for that date in that very cell and it'll be very helpful
if there's an icon in the cell instead of text (same as the icon you
get in MS word if u drag and drop an outlook object). And then I can
double click on that object to open the embeded object in outlook
itself !! Is that possible ?
A way that I thought, could be used to impliment this was to make the
cell, where i want to drop the object - a target cell. so after making
a target cell, if I drop something on the sheet after dragging the
object from outside of the sheet, the object should only drop in the
target cell and no where else. Is that possible in excel? I have
googled a lot but couldn't find anything.

Thanx again in advance
and my apologies for the long reply !!
regards,
