How to Block a Sender by Email Address in Outlook.com


Outlook.com logo
Microsoft Corporation

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, thankfully it must be said, comes from a special address.

In Outlook.com, you can block these easily and avoid future messages from the senders without effort.

If you have before you on the screen an email from the address you want to block, Outlook.com makes putting them on the list of unwelcome senders especially simple. Manually blocking any address — or entire domains — is not much more work, though.

Block a Sender by Email Address in Outlook.com

To delete all messages from a sender in your Outlook.com inbox (or another folder) and add them to you blocked senders list:

  • 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 go.
  • Click Sweep in the toolbar.
  • Select Delete all from… from the menu that appears.
    • As an alternative, you can also hover the mouse cursor over the sender's name in the message list, wait for the context menu to appear and select Delete all from… from it.
  • Make sure Also block future messages is checked.
  • Click Delete all.

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.

Block Any Email Address in Outlook.com

To add any address or domain name to your Outlook.com's list of blocked senders (without a message from the potential sender at hand):

  • Click the settings gear in your Outlook.com's toolbar.
  • Select More mail settings from the menu that shows.
  • Follow the Safe and blocked senders link under Preventing junk email.
  • Click Blocked senders.
  • Enter the unwanted address under Blocked email address or domain:.
    • To block mail from all addresses at a domain, enter just the domain name — typically what follows '@' in an email address.
      Adding "example.com" to the list, will, for instance, block messages from "me@example.com" as well as "you@example.com" and other addresses ending in "@example.com".
    • Note that you have to block sub-domains separately; "example.com" will not block messages from "she@location.example.com".
  • Click Add to list >>.

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

Note that 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 will teach the spam filters to recognize — and filter away — similar messages in the future. You can also report phishing scams, of course.
