while I am quite proficient coding in VBA in Excel, I am still a noob when it comes to Outlook. Please apologize, if I am asking something which is obvious to you.

I regularily receive meeting invites from specific users, which are blocking my calendar. I would therefore like to setup a VBA macro to automatically decline the meeting request, if it was sent by a specific user and a specific word is mentioned in the subject. My current Macro works "sort of", as it does not loop through all invites. Even if an invite from the specific user is found, the macro often does not get the corresponding calendar entry when running the
Set myAppt = myMtgReq.GetAssociatedAppointment(False) line.

Does anyone have a better ideo, or know what would need to be changed in my code below?

Sub DeclineSpamMeetings()
    Dim myNameSpace As Outlook.NameSpace
    Dim myFolder As Outlook.Folder
    Dim myMtgReq As Outlook.MeetingItem
    Dim myAppt As Outlook.AppointmentItem
    Dim myMtg As Outlook.MeetingItem
    Dim SenderEmail As String
    Dim i As Integer
    If DisableEvents = False Then
        Set myNameSpace = Application.GetNamespace("MAPI")
        Set myFolder = myNameSpace.GetDefaultFolder(olFolderInbox)
        DisableEvents = True
        For i = 1 To 10
            Set myMtgReq = myFolder.Items.Find("[MessageClass] = 'IPM.Schedule.Meeting.Request'")
            If TypeName(myMtgReq) <> "Nothing" Then
                If InStr(1, UCase(myMtgReq.SenderEmailAddress), "DOE.J") > 0 OrInStr(1, UCase(myMtgReq.SenderEmailAddress), "MUSTERMANN.F") > 0 Then
                    SenderEmail = myMtgReq.SenderEmailAddress
                    Set myAppt = myMtgReq.GetAssociatedAppointment(False)
                    If Not myAppt Is Nothing Then
                        If InStr(1, myAppt.Subject, "Project XY") > 0 Then
                            Set myMtg = myAppt.Respond(olMeetingDeclined, True, False)
                           MsgBox "Auto-Declined meeting (" & SenderEmail & ")"
                          End If
                    End if
                End If
             End If
        DisableEvents = False
    End If
    Set myAppt = Nothing
End Sub
Thanks for your help
