Instead of using the MAPIUtils object I'd recommend using an RDOMail object
for both tasks. You need an RDOSession object for that of course but I think
that's the better approach:

Redemption.RDOSession session = new Redemption.RDOSesison;
session.MAPIOBJECT = this.Application.Session.MAPIOBJECT;

// _missing is System.Reflection.Missing.Value, olMail is the Outlook mail
item
Redemption.RDOMail _mail = session.GetMessageFromID(olMail.EntryID,
_missing, _missing);

string recipEmail = _mail.Recipients[1].AddressEntry.SMTPAddress;
string senderEmail = _mail.Sender.SMTPAddress;

Hi:

I can get recipient's email by using Redemption:

Redemption.MAPIUtils utils = new Redemption.MAPIUtils();

utils.MAPIOBJECT = this.Application.Session.MAPIOBJECT;

int PrSMTPAddress = 0x39FE001E;

string AddresseeEmail =
(string)utils.HrGetOneProp(mail.Recipients[1].AddressEntry.MAPIOBJECT,
PrSMTPAddress);

Now I want to get sender's email address as well. mail.SenderEmailAddress
is not always as simple as . How do I get the sender address?
(mail is Outlook mailitem).



Thanks,



Danny Huang
