Quick and Easy:

- Troubleshooting tip: Check the connection status for Outlook. This can be done by holding Ctrl key and right-clicking the Outlook quick-launch icon in the system tray near the clock. Select connection status. The number of persistent connections utilized by Outlook will be displayed.
