Troubleshooting Outlook COM Addins – Using VBScript

Since Office uses COM to create Addins and _IDTExtensibility2 inherits from IDispatch it is available to scripting clients, a common technique I use to troubleshoot COM Addins are to see if I can create the component manually via a vbscript.  Use the following code to check whether or not COM can create your component:


Option Explicit

Dim objAddin
' Set this equal to the ProgId of your Addin
const ProgId = "Sample1.Connect"

Set objAddin = CreateObject(ProgId)

If Not objAddin Is Nothing Then
WScript.Echo "Successfully created your Addin!"
Set objAddin = Nothing
WScript.Echo "Error creating your Addin!" & _
Err.Description & " " & Err.Number
End If


Change the ProgId constant to be specific to your Addin’s ProgId and that is all that is needed.  Just save this code off to the file system and give it a .vbs extension and run the script using the following command:

cscript.exe <filename> **


** If you are running on a 64 bit system make sure you run the cscript.exe from %Systemroot%\SysWow64 and not %Systemroot%\System32.
