Hi All,

what can be reason for this??
i'm trying to retrieve commandsBar, and once in a while got this
strange exception
within Outlook 2003.

System.Runtime.InteropServices.InvalidComObjectExc eption: COM object
that has been separated from its underlying RCW cannot be used.
* *at Microsoft.Office.Interop.Outlook.ExplorerClass.get _CommandBars()

Any ideas??

Hi,

the reason for this is that you are using a COM object that is already
released.

Following code will throw that exception:

Outlook.MailItem mailItem = activeInspector.CurrentItem;
Marshal.ReleaseCOMObject(mailItem);
string mailItemSubject = mailItem.Subject;

Hope that helps,
Tobias

Thanks,

I see, however i access the Outlook excplorer's ui object.
You want to point that now even in Outlook (without any programming)
impossible to access the File Menu for example??
The Outlook is alive.
I don't understant this.

Please explain, thanks in advance.

If that happens even when you just use Outlook, maybe it's another Add-
In causing the problem. Try disabling installed Add-Ins.

There is no other addIns.
My question is if for expample i execute the following line of code:
-- myExplorer is active explorer
Marshal.ReleaseCOMObject(myExplorer.CommandBars);

so now, i'll failed to work with Otulook's Menu ??
