I use Outlook for email. It has just started acting up by giving me an "Operation Failed" error message when I press the Send / Receive button. I have tried the "repair" tool with no luck. I have reset and checked the email accounts and there is no problem with sending test messages. I have checked all the settings and they appear to be fine. It is only on one of my computers that are networked through a router hooked up to the same incoming cable connection. I'm out of ideas. Does anyone have a fix for this maddening problem?
