You didn't answer my question about what you mean by "detect the user". And
what version of Outlook are you programming against?

I meant that I want to see what users there is in the "users list" or
whatever it is. When I add a user to the recipients collection, I would
not need to use the whole name. For example, If I in outlook have the
main user called Robert Andersson, I would just have to use Recipient
Rec = (Recipient)oNS.CreateRecipient("Robert"). If I would like to see
the name for this user, I could use Rec.Name and it would display
Robert Andersson. So when I saw that this was possible I was sure that
this names must be stored somewhere, and thats what I need to find out
how to get those names. And I use Outlook 2003.
