Most mail is welcome; some is spam. A few messages are neither junk, though, nor welcome: the newsletter that sends to an address you don't recall and whose mailings you cannot seem to turn off, that mysterious sender who always forwards to about three million people — including you; or the auto-reply you never read that comes from a special address.

Using Outlook Mail on the Web and Outlook.com, you can block these easily and avoid future messages from the senders.

Block a Sender by Email Address in Outlook Mail on the Web

To set up a rule in Outlook Mail on the Web that deletes all messages from a sender and removes all current messages from the same sender, too:

  1. Open a message from the sender you want to block.
  2. Click Sweep in the Outlook Mail toolbar.
  3. Verify that Delete all messages from the Inbox folder and any future messages is selected on the sheet that has appeared.
  4. Click Sweep then OK.

Outlook.com will move all messages from the address or addresses in the current folder (but not in other folders – say, your archiving folder if you are in the Inbox) to the Deleted folder and add the sender or senders to your list of blocked senders.

To delete all messages from a sender in your Outlook.com inbox and add them to your blocked senders list:

  1. Open a message from the sender you want to block in Outlook.com. You can also check it in the message list without opening. If you check more than one message, Outlook.com will let you block all their respective senders in one step.
  2. Click Sweep in the toolbar.
  3. Select Delete all from the context menu. As an alternative, hover the mouse over the sender's name in the message list, wait for the context menu to appear and select Delete all from it.
  4. Verify that Also block future messages is checked.
  5. Click Delete all.

Outlook.com will move all messages from the addresses in the current folder (but not in other folders – say, your archiving folder if you are in the Inbox) to the Deleted folder and add the sender or senders to your list of blocked senders.

What Happens to Messages from Blocked Senders

Messages from senders on your blocked senders list will be discarded without notice. Neither you nor the sender will be notified, and the messages will not appear in your Deleted or Junk folders.

Blocking Senders and Domains to Block Spam

Blocking specific senders or domains is not a typically a way to stop junk emails. Spam rarely comes twice from the same address.

To combat spam, it is best to report junk emails that make it to your Outlook.com inbox. This procedure will teach the spam filters to recognize and filter similar messages in the future. You should also report phishing scams.
