You're confused, that makes three of us - We really don't know what the xbox 360 tools.exe does, I would have thought you would have been using a conventional email client (thunderbird, windows live mail, MS Outlook, etc. or your browser to browse your email.
So if as your email is being sent by MS Outlook, the question is what is the xbox 360 tools.exe doing trying to connect to gmail for if you use MS Outlook ?
