OutLook and GetSharedDefaultFolder problem

Reading shared calenders like 'TestRig 1', 'TestRig 2', 'TestRig 3' using .GetSharedDefaultFolder() worked as a charm until
'TestRig 11' and 'Test Rig 12' where added 😢.

'TestRig11 and 12 you can find but not TestRig1 anymore, using 'TestRig 1' is almost same as 'TestRig 11' only the last char is new.

The Fix: 'TestRig 1' is a view name, so changing to the real mail address instead testrig1@mytestcenter.com and the problem was solved 😀


The Code:

Sub ReadCalendarFromOutlook(calName As String)
        Dim application As New Microsoft.Office.Interop.Outlook.Application

        Dim myNamespace As Outlook.NameSpace
        Dim myRecipient As Outlook.Recipient
        CalDay1.Scroll2Time(Now)
        CalDay1.SetupTimeLine()
        CalDay1.ClearAllEvents()
        lblCalInfo.Visible = False

        If calName = "" Then
            lblCalInfo.Visible = True
            lblCalInfo.Text = "No Calendar available"
            Exit Sub
        End If
        Try
            myNamespace = application.GetNamespace("MAPI")

            myRecipient = myNamespace.CreateRecipient(calName)

        Catch ex As Exception
            MsgBox("It looks like you are missing OutLook on the computer :(")
            Exit Sub
