How to Take Control of Your Outlook Inbox

Managing an inbox filled with messages you don’t want (or need) is frustrating. Outlook offers several methods to block email addresses, making it easier to stay organized and focused. 

How to Block a Sender in Outlook Desktop

Blocking a sender in the desktop version of Outlook only takes 4 steps. This method ensures that emails from unwanted contacts do not appear in your inbox.

Steps:

1. Open Outlook and select an email from the sender you want to block
2. Click Junk on the toolbar
3. Select Block Sender
4. Confirm the action

Future emails from this sender will go directly to your Junk Email folder before being automatically deleted

Tip: If you use Outlook 2016, 2019, or Microsoft 365, the steps are the same. For older versions, check the Help section under “Junk Email Options.”

How to Block an Email Address in Outlook Web App

The Outlook web app allows you to block unwanted emails directly in your browser. This is helpful if you don’t have the desktop app installed.

Steps:

1. Log in to Outlook.com
2. Open an email from the sender you want to block
3. Click the three-dot menu in the top-right corner of the email
4. Select Block
5. Confirm - this will send future messages from this address to your Junk Email folder

iOS and Android Steps:

4. Select Block Sender

The sender will no longer be able to send messages to your main inbox.

How to Permanently Block an Email

Looking to say ‘goodbye’ to a specific sender forever? Here’s how you manage your blocked senders list:

1. In Outlook Desktop, go to Home > Junk > Junk Email Options
2. Navigate to the Blocked Senders tab
3. Add any email addresses you want to block permanently

You can remove addresses from this list if you decide to receive emails from them again in the future.

Tip: You can also set up Outlook rules to automatically delete messages containing specific words, domains, or phrases. This adds another layer of inbox protection.
