Outlook Blocked Email Addresses: Block and Manage Senders

If you're tired of receiving unwanted emails in Outlook, you can block specific senders to keep your inbox clutter-free. Blocking email addresses in Outlook is a simple process that can be completed in a few steps.

To block an email address, you can right-click on the sender's name in the email header and select "Block sender" from the context menu. This will prevent future emails from that sender from reaching your inbox.

Blocking senders is a great way to manage unwanted emails, but it's not the only option. You can also use Outlook's junk email filter to automatically block spam emails. To access the junk email filter, go to the "Home" tab and click on the "Junk" button in the "Delete" group.

The junk email filter can be adjusted to suit your preferences, allowing you to choose how aggressive you want the filter to be. By setting the filter to a higher level, you can reduce the amount of spam emails that make it to your inbox.

If you're having trouble adding emails to your blocked senders list in Outlook, it might be because of the way the email is formatted. The "FROM" field shows the sender's name, but the "TO" field shows the recipient's email address, which is not your own.

It's worth noting that the emails you're trying to block are coming from legitimate businesses, but with fake sender names and email addresses. This can make it difficult to identify the actual sender and block them.

Try using the "Force Email" field to see the real email address, and see if that helps you identify the sender. This field can give you a better idea of who's really sending the email.

If you're having trouble adding emails to your blocked senders list, it might be due to a limitation on the number of blocked senders you can have. This is a known issue.

You can manually add names or domains to your Safe Senders or Safe Recipients Lists, but if your mailbox is hosted on Exchange or Exchange Online, changes you make to the Safe Senders list may not be recognized. This can result in messages from trusted domains or senders ending up in your Junk Email folder.

If you're using Outlook 365, you can try adding the sender's email address or domain to the Safe Senders List by selecting a message from the sender, going to the Home tab, and selecting Block, then Never Block Sender.

However, if you're receiving spam emails with fake "FROM" fields and real email addresses in the "FORCE EMAIL" field, you might be running into a different issue. These emails may not be getting added to your blocked senders list because they don't have your email address in the "TO" field.

These types of emails might be slipping through the cracks, but you can try to add the real email address in the "FORCE EMAIL" field to your blocked senders list.

The Blocked Senders list in Outlook can be a bit finicky, but understanding the cause of some issues can help you troubleshoot more effectively.

The issue occurs if the Blocked Senders list domain entries were created through Outlook, and if they do not begin with the @ sign.

This is because Outlook provides additional Blocked Senders functionality for the inclusion of subdomains when the @ sign is not present in the Blocked Senders domain entry.

For example, an entry like contoso.com will filter not only contoso.com but also subdomain1.contoso.com, subdomain2.contoso.com, and subdomain3.contoso.com.

This helps prevent spam from being delivered to the Inbox when the subdomain portion of the email address has been randomized.

Subdomain filtering for a Blocked Senders domain is a client-side feature and is available only in Outlook, not through Outlook Web App on Exchange Server.

To illustrate this, the following entries are displayed in the Blocked Senders list in both Outlook and Outlook Web App: @contoso.com and @wingtiptoys.com. However, the following entries are displayed in the Blocked Senders list only in the Outlook client, not in Outlook Web App: contoso.com and wingtiptoys.com.

If you're having trouble with blocked senders not being recognized by Outlook Web App and Exchange Server, the solution is to include the @ sign at the beginning of the Blocked Senders domain entries.

To do this, go to the Home tab on the ribbon and select Junk E-mail Options. On the Blocked Senders tab, select Add and enter the domain entry, including the @ sign. For example, if you want to block the domain "example.com", you would enter "@example.com".

This will ensure that the blocked sender is recognized by both Outlook and Exchange Server.

Blocking a sender in Outlook may seem like a simple solution to reduce spam, but it's not without its drawbacks.

Blocking a sender only redirects their emails to the Junk Email folder, where they still take up space and clutter your email account.

You can block a sender by right-clicking on one of their emails and choosing Block > Block Sender, or by clicking on the three dots icon and selecting Block from the drop-down menu.

There's a limit to how many senders you can block, with Microsoft Exchange Server accounts only allowing 1024 addresses for the Blocked Senders list, Safe Senders and Safe Recipients lists combined.

Spammers often use different email addresses to evade detection and filters, making blocking a sender less effective than other methods.

If you're tired of receiving unwanted emails from specific countries, you can block messages by country/region code in Outlook.

You can block messages from particular countries or regions by adding their codes to the Blocked Top-Level Domains List. This list lets you block messages from email addresses that end in a particular top-level domain or country/region code.

For example, selecting the CA [Canada], US [United States], and MX [Mexico] check boxes in the list blocks messages that come from email addresses that end in ca, us or mx.
