There are a few strategies that you can try to correct this situation. Complete one at a time until you resolve the problem. If this only happens once in a while, it could be a problem with the Internet connection. If it happens all of the time, then try these suggestions.
Troubleshooting Connecting to MSN Messenger: Clear Stored Internet Data
One of the easiest methods for resolving problems with websites is to clear the Internet cache, history, cookies, etc. While this does not work all of the time, it is great when it does. How you go about it varies according to your web browser. Typically, you can navigate to the “Tools” section of your browser and search there to clear your private data including Internet cache, history, cookies, and passwords.
Troubleshooting Connecting to MSN Messenger: Verify Your Log in
Even if you think this next step isn’t going to help, it doesn’t take that long to complete. Visit the website for MSN and access your password so that you can make sure that you are using the correct one. You should use the Windows Live ID Validation Form to do so.
Troubleshooting Connecting to MSN Messenger: Update Your Web Browser
It is vital in this time of fast-changing technology to constantly check for updates not only for your operating system, but also for your web browser. Visit the website for whatever browser you are using and check to see if any current updates exist. Download them if you haven’t already done so. While you are at it, you can also check for updates for your operating system.
Troubleshooting Connecting to MSN Messenger: Check the Security Settings
It’s important to note that whenever you update your operating system, applications, or web browsers, you might need to change some of your settings as they might have changed during the update. Take the time to browse through your settings and make sure that you don’t have your security level set too high since this is one of the more common changes.
Troubleshooting Connecting to MSN Messenger: Scan for Viruses and Spyware
If your computer is infected with a virus or spyware, it could explain the problem connecting to MSN. Scan your computer with a reliable anti-spyware/anti-virus application. If you don’t have one, I can suggest Anti-Virus PLUS. If you do have one, update it first so that it is current.

Basically, no. Unless that user is logged onto a particular computer, you can’t see their conversations on that computer. There is no option through MSN to basically “snoop” on other people’s accounts and see what they are talking about with other people on a different computer. If you have your computer set correctly, MSN will save a history of conversations that take place on that computer using that user’s password.
