I found that there were some items in my inbox that were not mail items causing the script to halt.
This little change allowed the script to keep running if something like a meeting invite is found:
Sub getmail()
Dim olApp As Outlook.Application
Dim objNS As Outlook.Namespace
Dim olFolder As Outlook.MAPIFolder
'Dim msg As Outlook.MailItem
Dim InboxItem As Object
Set olApp = Outlook.Application
Set objNS = olApp.GetNamespace("MAPI")
Set olFolder = objNS.GetDefaultFolder(olFolderInbox)
Set olFolder = olFolder.Folders("temp")
For Each InboxItem In olFolder.Items
Debug.Print InboxItem.Subject
Debug.Print InboxItem.EntryID
Next
End Sub
Thanks for your answer! helped me a lot!
