When i was trying to run a vb application i got error in the following line.

set obj = createobject("MAPI.Session")

runtime error - 2147467259
automation error
unspecified error

can anyone help on this?

I gave reference to CDO 1.21 also

Thank You,
Louis

I think this could be a problem with your late binding. The mapi functionality looks to be ordinarily exposed by an ocx rather than a dll - therefore it is a control you have to add to a form.
