MAPI Illegal operation

Hi guys,

I'm getting the error "This program has performed illegal operation error" when I access even a simple property of Mapi.session object. My deafault mail client is Outlook.

eg. The following code displays the CurrentUser name but after dispaying it, VB gets closed by saying "This program has performed illegal operation"

Private Sub Command1_Click()
Dim oSession As Mapi.Session
Set oSession = New Mapi.Session
oSession.Logon "", "", False, False
MsgBox oSession.CurrentUser
Set oSession = Nothing
End Sub

Can anyone suggest me what to do ASAP?

Thank you,
Sandeep

Add

VB Code:

oSession.Close

Before setting it = nothing...

Hi James,

There's no method called close in the Session object. Instead I tried using oSessiojn.Logoff. But the problem still persists.

Here's my email code that I use :
