How can I retrieve SenderAddress by SenderName?

Answer:

Sometime ago I posted a few tips for MS Outlook automation. I want to continue this 
serie. 

If you tried to work with messages from Delphi, you know that received message have 
the SenderName property (name of sender) but doesn't allow to read the real address 
of sender. Something like SenderAddress is not  available. 

Exists a few methods to retrieve this information: 

1. help file says that sender is in Recipients collection with Type property - 0 
(olOriginator). But this way is not work for any version of MS Outlook. So just 
iterate thru collection of Recipients and find an item with Type=0 couldn't return 
required value 

2. as alternative you can read a ReplyTo property - there you'll receive an address 
(but generally ReplyTo and Sender could be different). For example, in messages 
which I send from own mail account these values are 
different. 

3. to create a new MailItem (just will be destroyed without saving in end of work), 
define a Recipient as value which you received from SenderName of your original 
message and call a Resolve method - after that you'll recieve a correct email 
address of this sender. 

4. more correct and fast solution is the next: 

1   begin
2     objCDO := CreateOLEObject('MAPI.Session');
3     objCDO.Logon('', '', False, False);
4     objMsg := objCDO.GetMessage(itemOL.EntryID, itemOL.Parent.StoreID);
5   
6     s := objMsg.Sender.Address;
7     showmessage(s);
8     objMsg := UnAssigned;
9     objCDO := UnAssigned;
10  end


where itemOL is a MailItem which contain a SenderName but doesn't contain a SenderAddress:-)
