Block or unblock a sender

Applies To: Outlook for Mac 2011

If you want to stop receiving e-mail from someone, you can add his or her e-mail address to your blocked senders list. Outlook automatically moves any new mail that you receive from this person to the Junk E-mail folder. When you want to receive mail from this person again, you can remove his or her e-mail address or domain from your blocked senders list.

Do any of the following:

Block a sender

  1. In the message list, select a message from the sender whom you want to block.
  2. On the Hometab, click Junk, and then click Block Sender.
