When I close fiddler, I can access to outlook; while using fiddler, I fail to visit it with the error message below:

Hello Lorraine Xu,
Most Office365 products, including Outlook, are not handling the system proxy's dynamic change very well. That said, the best approach is explicitly bypassing them within Fiddler so that their traffic goes directly upstream.
You can open Fidder Classic > Tools > Options > Connections and bypass the below endpoints in Bypass Fiddler Classic for URLs that start with: field.
*office.com;*office365.com; *live.com;*outlook.com;autodiscover.yourcompany.com
You need to replace yourcompany with the domain address used by your organization. After the change, ensure that your Outlook is fully restarted so that the change can take place.
