Pindionline.com MSN ONLINE STATUS CHECK

Enter any MSN Messenger account's e-mail in the field below and press the "Check" button to find out,  that the person is online at the moment or not.

If it shows the online icon and you've added the person to your contacts but he or she ISN'T listed as online, you can be sure you're being blocked by him or her!
On the other hand, the offline icon doesn't necessarily mean the person is *really* offline, so you might have been blocked too. That's because there's an option in MSN Messenger (Options > Privacy > My block list) to block anyone that was not added to yet, including this Online Status Checker.
