Exchange Web Services has a ResolveNames() function that I can use to retrieve (among other things) the primary SMTP address for the Active Directory user that logged on to
I found it. I have to go through the Accounts object in the namespace:
for i := 1 to lNameSpace.Accounts.Count do
if lNameSpace.Accounts.Item[i].AccountType = olExchange then
begin
lAccount := lNameSpace.Accounts.Item[i];
Break;
end;
if VarIsClear(lAccount) then
begin
DisConnectFromOutlook;
Exit;
end;
lLoginSMTP := lAccount.SmtpAddress;
The only thing I would still like is to determine the default account.
