I must make it clear that this little tip is for beginner’s only. You must have experienced that many of your contacts have multiple email accounts and its quite irritating to see your address book filled with multiple entries of the same person. The reason is, Windows Live Hotmail treats every email address as a unique contact and this makes your address book unorganized and cumbersome to use. However, Windows Live Hotmail offers a feature to counteract this issue.

Here’s how you can either merge multiple email IDs of the same contact or delete all but one of their email IDs:

1) In your Windows Live Hotmail account, click ‘Options’ > ‘More options’.

2) Now, under the ‘Customize your contacts’ category, click ‘Clean up duplicate contacts’.

3) Then click the ‘Clean up duplicate contacts’ button and select a contact from the list.

4) Now you can either select all but one contact details and delete the rest or you can select all and merge them.

There you are. You just made your address book much more clean and well-organized.
