| Blocking Chat Messages | Unblocking Chat Messages | Chatting with Windows Live Users | If You Use Yahoo! Messenger |
There always seems to be a few unwanted, uninvited people who find a way into your space. Yahoo! Mail lets you block unwanted chats.
If a chat arrives from someone who isn’t in your Yahoo! Contacts, Yahoo! Mail displays an alert in the chat window. To block the sender, do the following:
Click the Block Sender link.

A confirmation window opens where you can confirm the block or cancel it.
Confirm the block by clicking the Block button.

The conversation tab goes away, and a message tells you that the sender’s ID has been added to your Blocked list.
Tip: If you click the Show Message link, the chat window displays the message. You can chat with the person and add the person’s information to your Yahoo! Contacts by clicking the Add button.
If you want to block a contact while chatting, do the following:
Click the Block Sender link in the upper-right corner of the chat window.

A confirmation window opens letting you know that you will no longer receive chat messages from this person. If the person’s name is on your Messenger List, it will be removed from the list.
In the confirmation window, click the Block button.

The chat window goes away, and a message tells you that the sender’s ID has been added to your blocked list.
Don’t worry, if someone you’ve blocked from chatting gets back on your good side, you can unblock his or her ID and chat away.
