Hello everybody,

I try to export mails from my Outlook inbox with C#.
I try it with this statement:
for (int i = 1; i <= outlookApp.ActiveExplorer().CurrentFolder.Items.Count; i++)
{
outlookApp.GetNamespace("MAPI").GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox).Items.Item(i)
}

But all what I get are this reference: System.__ComObject. How can I get the parts of the mail (e.g. subject, body and especially an flag if the mail is new).

Regrads!

Hi Peppi,

Try the following code to get mail items in Outlook.
In order to check whether a mail item is a new mail you can use the Sent property of Outlook.MailItem interface. If it returns false it means this is a new mail.

private void adxCommandBarButton1_Click(object sender)
{
Outlook.Items items = null;
Outlook.MAPIFolder folder = null;
Outlook.MailItem mail = null;
Outlook.NameSpace namespace_ = null;
string body = String.Empty;
string subject = String.Empty;

try
{
namespace_ = OutlookApp.GetNamespace("MAPI");
if (namespace_ != null)
{
folder = namespace_.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
if (folder != null)
{
try
{
items = folder.Items;
for(int i=1; i<=items.Count; i++)
{
mail = items.Item(i) as Outlook.MailItem;
if (mail != null)
{
subject = mail.Subject;
body = mail.Body;
Marshal.ReleaseComObject(mail); mail = null;
}
}
}
catch(Exception e)
{
if (mail != null)
{
MessageBox.Show(e.Message, e.Source, MessageBoxButtons.OK, MessageBoxIcon.Error);
Marshal.ReleaseComObject(mail); mail = null;
}
}
}
}
}
finally
{
if (items != null)
Marshal.ReleaseComObject(items);
if (folder != null)
Marshal.ReleaseComObject(folder);
if (namespace_ != null)
Marshal.ReleaseComObject(namespace_);
}
}

Hi everybody,

@ Sergey: Now I understand how it works. But I've got one problem. Which Reference I have to add for the Marshal-class?

Regrads!

You should use Marshal class with System.__ComObject references.
See MSDN: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemruntimeinteropservicesmarshalclassreleasecomobjecttopic.asp
You can see in the debug mode what happens with System.__ComObject reference after the Mashal.ReleaseComObject method was applied to it.

Peppi,
I mean that you should use Marshal class with references that store COM interfaces, e.g Outlook interfaces.

Hi everybody,

@ Sergey: Now I understand the sense of the marshal-class. Thank you!

Is there the possibility to find out which mails in my Outlook inbox are marked (tagged). I only want to get the subject, body et cetera of these mails.

Regrads!

Hi Patrick,

Outlook._MailItem interface has the FlagStatus property. This property can return the following values:
olFlagComplete
olFlagMarked
olNoFlag
I hope it will help you.

Hi Sergey,

I try to use this property, bu it don't run.
for(int i=1; i<=items.Count; i++)
{
mailItem = items.Item(i) as Outlook.MailItem;
MessageBox.Show(mailItem.FlagStatus);
}

But if I marked a mail in the Outlook Inbox (by clicking it) and I run through all MailItems (with my Programm) the value of the FlagStatus is allways olNoFlag. ???

Hmmm... it is very strange, because I use the following code and I get flags correctly.

private void adxCommandBarButton2_Click(object sender)
{
object selectedItem = null;
Outlook.Selection selection = null;
Outlook._Explorer activeExplorer = OutlookApp.ActiveExplorer();
Outlook.MailItem mail = null;
try
{
if (activeExplorer != null)
{
try
{
selection = activeExplorer.Selection;
if (selection.Count > 0)
{
selectedItem = selection.Item(1);
if (selectedItem is Outlook.MailItem)
{
mail = selectedItem as Outlook.MailItem;
MessageBox.Show(mail.FlagStatus.ToString());
}
}
}
catch
{
}
}
}
finally
{
if (selectedItem != null)
Marshal.ReleaseComObject(selectedItem);
if (selection != null)
Marshal.ReleaseComObject(selection);
if (activeExplorer != null)
Marshal.ReleaseComObject(activeExplorer);
}
}

What version of Outlook do you use?
