Needs Help With VBA Reference for Outlook

Noah used Ask the Experts™
Greetings experts,

I am currently trying to automate tasks between Excel and Outlook, however, there seems to be a recurring issue.

I keep getting the "user-defined-type-not-defined" error despite already having ensured that the Microsoft reference under the Tools tab has been checked.

The line that the code appears to have this error is something like this
Dim App As New Outlook.Application

Open in new window

Any help is much appreciated! :)

are you sure you have the correct version of the outlook library installed on the PC ?  And selected ?

I just tried your code and got the error when the outlook library was NOT selected.

worst case, you could use late binding
    Dim app As Object
    'Set app = New Outlook.Application
    On Error Resume Next
    Set app = GetObject(, "Outlook.Application")    '.CreateObject("Outlook.Application")
    Debug.Print Err.Number
    If Err.Number <> 0 Then
        Set app = CreateObject("Outlook.Application")
    End If
    On Error GoTo 0
    Debug.Print app.Version

Open in new window
