Hi,
I have a situation where I want to modify an existing item in Outlook,
but I cant get the recipients to work properly when using Redemption.

First I create a new mail item, add some properties (like subject,
recipients etc), get hold of the EntryID and exit.
Later on I reconnect and find the mailItem using GetItemFromID and
start modifying this Item.

Changing the Subject works just fine, but I cant seem to get the
Recipients modified correctly.
When I add a recipient it is apparently added, using OutlookSpy to
view the "CurrentItem.To" property I can see all my recipients.
However, the ones I added when I modified the Item is not visible in
Outlook and if I manually enter a new mailaddress (in Outlook), the
ones I added in the modification code disappears from the
"CurrentItem.To" property in OutlookSpy as well.

If I use Outlook directly (no Redemption code), I can get this
working, but I dont want the Security message box, so it is not really
an alternative.

I created a small sample program that demonstrates this problem:

using Outlook = Microsoft.Office.Interop.Outlook;
using Interop.Redemption;

private void main()
{
string entryID = RedemptionCreateTestMail();
RedemptionAddRecipient(entryID);
}

private string RedemptionCreateTestMail()
{
Outlook.Application olApp = new Outlook.Application();
Outlook.NameSpace olNS =
(Outlook.NameSpace)olApp.GetNamespace("MAPI");
olNS.Logon("", "", false, true);

Interop.Redemption.SafeMailItem safeItem = new
SafeMailItem();
Outlook.MailItem mailItem =
(Outlook.MailItem)olApp.CreateItem(Outlook.OlItemT ype.olMailItem);
safeItem.Item = mailItem;

");
safeItem.Recipients.ResolveAll();
mailItem.Subject = "Mail Created";
mailItem.Save();
mailItem.Display(false);

string entryID = mailItem.EntryID;

mailItem = null;
safeItem = null;
olNS.Logoff();
olNS = null;
olApp = null;

return entryID;
}

private void RedemptionAddRecipient(string entryID)
{
Outlook.Application olApp = new Outlook.Application();
Outlook.NameSpace olNS =
(Outlook.NameSpace)olApp.GetNamespace("MAPI");
olNS.Logon("", "", false, true);

string storeID =
olNS.GetDefaultFolder(Outlook.OlDefaultFolders.olF olderInbox).StoreID;
Outlook.MailItem mailItem =
(Outlook.MailItem)olNS.GetItemFromID(entryID, storeID);

Interop.Redemption.SafeMailItem safeItem = new
SafeMailItem();
safeItem.Item = mailItem;
");
safeItem.Recipients.ResolveAll();

mailItem.Subject = "Attached to mail: " + entryID;

mailItem.Save();
mailItem.Display(false);

mailItem = null;
safeItem = null;
olNS.Logoff();
olNS = null;
olApp = null;
}

Outlook cannot see any changes made with Extended MAPI until you completely
dereference and reopen the item.
For some reason Outlook refereshes it internal cache of recipients when you
add a user property (you can immediately delete) it after you add a
recipient but before you display it.

");
safeItem.Recipients.ResolveAll();
prop = mailItem.UserProperties.Add( "test", 1 );
prop.Value = "test";
prop.Delete();
mailItem.Subject = "Mail Created";
mailItem.Save();
mailItem.Display(false);

Very useful. How on earth did you ever figure that out?

The usual head scratching "why does this work in one place but not in
another?" :-)
