Getting COMException when accessing on Outlook 2010

Question

Hi All,

 

Error :-

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80010001 Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED)).

 

My Code: 

 

private static Microsoft.Office.Interop.Outlook.NameSpace mapiNameSpace = null;

Outlook.Application myApp = new Outlook.Application();

mapiNameSpace = myApp.GetNamespace("MAPI");

 

The second line, throws an error message:-  

Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80010001 Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED))

 

Do you know any solutions?
