Outlook cannot connect without Fiddler running

[brian]

I have been using Fiddler to debug some application https communication (from C# & C++ apps in Visual Studio, Java apps in Eclipse, and Android apps in the emulator).  I managed to enable Fiddler for all of those scenarios, but in retrospect I should have written down what I was doing each step of the way.

Now, I find that unless Fiddler is running my outlook won't connect.  Gah!  (All of my browsers work with or without Fiddler ... it just seems to affect Outlook)

I'd like to be able to access my email without starting Fiddler...

Hi, Brian--

Without Fiddler running, what do you see inside Internet Explorer's Tools > Internet Options > Connections > LAN Settings screen?

Without Fiddler running, what do you see if you go to a command line and type netsh winhttp show proxy

I trust that you have restarted Outlook without Fiddler running?

If neither of those helped, please tell me what version of Windows and what version of Outlook you are using.

thanks,

Came across this problem today.  LAN settings are totally empty (no options selected, no proxy).

Current WinHTTP proxy settings: Direct access <no proxy server>.

And yet, I cannot connect to the Exchange server without Fiddler running. Stop Fiddler, Outlook disconnects from the Exchange server. Start Fiddler, Outlook connects to the Exchange server.  I believe the problem started when my PC crashed when both Outlook and Fiddler were running.

Any solution to this?

The chances are Outlook stored proxy address. You might try making Fiddler run on a different port to confirm that. Fixing Outlook, however, is not really something we can provide good advise on.
