IMapiSession exception: Specified cast is not valid
I'm using Mapi33... trying to get IMapiSession reference using the code
below... IntPtr iunknownPtr = Marshal.GetIUnknownForObject(m_OutlookApp.Session. MAPIOBJECT); IMAPISession imapiSession = (IMAPISession)iunknownPtr; where m_OutlookApp is an instance of Application from MS.Office.InterOp... When I run this code inside Outlook via Addin passing m_OutlookApp from OnConnection... it runs fine, when I run it from command app, passing an instance of m_OutlookApp using new Application() I get: System.InvalidCastException was caught Message="Specified cast is not valid." Any idea why or a workaround on how to get an IMapiSession reference from command line app? Thanks in advance

Did you call MAPIInitialize on that thread?
