How to Block Unwanted Emails and Senders in Microsoft Outlook

by Tony Holowitz | Aug 31, 2026 | ACT CRM Software Tips and Tricks

Unwanted email can clutter your inbox and distract you from important messages. Outlook includes a simple way to block repeat senders and manage your blocked-sender list.

Block a Sender

Right-click the unwanted message, open the Junk options, and choose Block Sender. Outlook will treat future messages from that address as junk. Review your blocked-sender settings periodically in case a legitimate address was added accidentally.

Key Takeaways

  • Block repeat senders directly from an unwanted message.
  • Review the blocked-sender list when expected email stops arriving.
  • Use unsubscribe for legitimate mailing lists you no longer want.
  • Continue treating suspicious messages cautiously.
