Microsoft 365 from GoDaddy Help

Block a sender in Outlook

If your inbox is inundated with email from unwanted senders, you can block them, sending their email to the Junk folder. The sender will not be notified that they're blocked.

Select the appropriate tab based on the email platform that you're using. If you want to block senders by domain, use Outlook for Windows or Outlook for Mac.

  1. Sign in to Outlook on the web. Use your Microsoft 365 email address and password (your GoDaddy username and password won't work here).
  2. Select an email from the sender you want to block.
  3. Determine whether you're using the Classic or Simplified ribbon.
    • If you're using the Classic ribbon: Select Block, and then Block sender.
      Select Block and then Block sender
    • If you're using the Simplified ribbon: In the upper-right corner of the message preview, select The More actions button at the top right of the email More actions, then Block, and then select Block again.
  4. To confirm that you want to send future emails to the Junk Email folder, select OK.
    Select Ok to confirm the blocked sender

Future emails from this sender will be sent to junk. If you want to undo this action, repeat these steps, but instead, during step 3, select Never block sender.

There are now 2 versions of Outlook for Windows: new Outlook and classic Outlook. Before continuing to the steps below, check which version you’re using.

New Outlook

If the steps in this section don't work, you might not be using new Outlook yet. Try the steps in the Classic Outlook section instead.

Required: To use new Outlook for Windows, it must be activated with a Work or school account licensed for Office desktop apps. (For Microsoft 365 from GoDaddy plans, it must be a Business Professional or higher plan. However, the license can be provided by any Work or school account.)

Upon activation, you can add additional email plans, such as Email Essentials, Email Plus, or Online Business Essentials.
  1. Open Outlook.
