User complains that Outlook does not accept their password. The error they are getting says that the SSL certificate is invalid. Also, when they access the SSL related sites it’s extremely slow.
If you take a look at the Certificates on their computer. (Go to mmc.exe and add the Certificates add-in), you will see hundreds of entries that says DO_NOT_TRUST_FiddlerRoot. First of all, delete those entries that says DO_NOT_TRUST_FiddlerRoot, if you did not install the FiddlerRoot yourself. Those are the culprit of your slowdowns.
Delete the FiddlerRoot program from your PC. In one case, program called BrowserSafeGuard.exe is reponsible for the FiddlerRoot. Uninstall it from the Control Panel.
Also, check the proxy in your Internet Explorer. Disabling the proxy entry will fix your Outlook problem.
