Voice mail message not forwarding

I set up the Voice Mail Notification Options under Phone Tools --> Settings to send me an email when someone leaves me a voicemail.  Up until a couple of weeks ago it was working perfectly but now I'm not getting notified.

I typed in the email address again then when that didn't work I inputted a different email address.  I turned the setting off and then on again and it still didn't work.  Now I cannot even get into the settings.  They said they moved it up to tier 3 but that was last week.

The caller is able to leave a voice mail and I can retrieve it fine, it's just the notification that isn't working.  I called tech support and they said they weren't able to troubleshoot it.  Any help would be appreciated.
