Search for an MSN Email Address With a Reverse Email Service
Like those with some Yahoo addresses, some with Hotmail or MSN addresses have had them for a very long time. This makes searching for those particular addresses much easier than ones that are newer to the scene. This is because as time passes, those who have these addresses are more likely to have them listed somewhere online where they can be found through various sources.
If you have a suspicion that you know the person behind the email address, you can first do a forward search on a search engine. Use a formula like name +email to see if you can find a match. If not, switch to reverse search by putting the email address into the search box to see what comes up. Though not all Hotmail addresses are going to come up, you may find the one you need with even more information.
You may also want to take that MSN or Hotmail email address to the search functions that you find on social and professional networking sites. This works because people tend to list their emails on professional networks, and they use their email address to sign up with most of them. Those email addresses are searchable. Try MySpace, FaceBook, Hi5, LinkedIn, and Orkut, just for starters.
You can also turn your search for an MSN or Hotmail email address to a more specific type of search tool. There are some sites that offer a comprehensive reverse email search that can find addresses that you may not find elsewhere. These work for older addresses very well, but can also pull up newer ones too.
