    I have fiddler v5.0.20173.50948 

    I was recently migrated at work to Outlook 2016 (version 16.0.9001.2080) and an Office 365 mailbox.

    When fiddler is active and capturing traffic, I will periodically (approximately every half hour or so) have Outlook attempt authentication, only to pop a dialog that says

        "You'll need the internet for this"

    with an error code of 0xCAA70004

     

    and outlook will no longer function, unless I turn off fiddler capture & restart Outlook.

     

    I am capturing and decrypting HTTPS traffic, but only for the hosts related to my work as a developer. I tried to relax filters to see all HTTPS traffic and I don't see where fiddler is getting in the way of Outlook.

     

    I have tried disabling IPv6 (tools / options / general), and the steps on http://toenailclippings.idealworld.net/2016/10/we-are-unable-to-connect-right-now/

     

    Neither have worked. Thanks for the help.

    Hi,

    Unfortunately, I'm unable to reproduce the problem you have. However, I will try to provide you with a workaround, so you are not blocked by this.

    In order to view all sessions (including filtered ones) you can go to Help -> Troubleshoot. All sessions that are going to be filtered in "non-troubleshooting" mode will be written with strike-though font. Then you should be able to see the Outlook sessions. Then you can go to Tools -> Options -> Connections and add the Outlook URL in the "Bypass Fiddler for URLs that start with" field. When done, go to Help -> Troubleshoot to disable the "troubleshooting mode".

    Regards,
