Could not load file or assembly Interop.MAPI

[Dhananjay]

Hi All,
I am developing one VSTO addin for office 2007 in VB 2005. I have used
CDO. As per suggesion on MS site, I have given strong Name to my
addin. My addin is shown in the ol2007 perfectly, but when I tried to
open a custom form with clicking on my commandbar button, I am getting
the error as

"Could not load file or assembly Interop.MAPI, version = 1.21.0.0,
culture = nutral , publicKeytoken = ...... Or one of its dependancies.
Failed to grant permission to execute. ( Excception for HRESULT:
0x80131418)"

In my click event of the custom button, I have used some CDO
statements like
Try
Dim msg As MAPI.Message
Dim ses As New MAPI.Session
ses.Logon("", "", False, False)
msg = ses.GetMessage(myCurrentItem.EntryID)
If msg IsNot Nothing Then msg.Delete()
ses.Logoff()
msg = Nothing
ses = Nothing
Catch ex As System.Exception
AddTrace("Error while deleting mailitem - " & ex.Message)
End Try
Where am I wrong?

Thanks,
Dhananjay

Thanks Dmitry for you reply,
So can't we use CDO 1.21 library from office 2003? Next, my code was
working perfectly when my project was in Shared Addin, but when I
changed the project to VSTO, I am facing those problems.
Further, I need to delete specific mail. I used above code snippet
for deleting the mail that I have currently opened. I used previously
myMail = Application.session.GetItemFromId(CurrentItem.EntryId)
for finding the currentItem, but it was giving me the value in myMail
as nothing.
So please can you tell me that how I can achieve the same effect in ol
model?

Thanks again
