I have a 500V2 with 5.0.26 and VMPro with 5.0.30. One user states that she gets a vm, gets the email, deletes the vm on the phone, then gets the MWI and the same email for vms a week later. That may be the strangest thing I have ever heard. I could not locate any duplicate extensions or groups. She is not in any hunt groups. The system doesn't show any errors. Weird.
