Managing blocked senders in Outlook 365 keeps your inbox free from unwanted messages and spam. Knowing how to view blocked senders in outlook 365 is essential for maintaining control over your email experience. This guide will walk you through every step, from finding the list to editing it, so you never miss an important message again.
Blocked senders are email addresses or domains you have marked as junk. Outlook 365 automatically moves their messages to your Junk Email folder. But sometimes you need to check who is on that list, or maybe you want to unblock someone by accident. Let me show you exactly how to do it.
Why You Need To View Blocked Senders In Outlook 365
Your blocked senders list is like a bouncer for your inbox. It stops unwanted emails from reaching you. But over time, this list can grow. You might block a legitimate sender by mistake, or you may simply want to review who you have blocked.
Viewing the list helps you:
- Confirm that a specific sender is blocked
- Unblock someone you now trust
- Clean up old or duplicate entries
- Ensure important emails are not being filtered out
Without checking, you could miss a job offer, a confirmation email, or a message from a friend. That is why knowing how to view blocked senders in outlook 365 is a skill every user should master.
How To View Blocked Senders In Outlook 365
Now let us get to the main part. There are several ways to view your blocked senders list depending on which version of Outlook 365 you use. I will cover the web version first, then the desktop app, and finally the mobile app.
View Blocked Senders In Outlook 365 Web
The web version is the most common way people access Outlook 365. Follow these steps:
- Open your browser and go to outlook.office.com
- Sign in with your work or school account
- Click the gear icon in the top-right corner to open Settings
- At the bottom of the Settings pane, click View all Outlook settings
- Select Mail from the left menu
- Choose Junk email
- Under Blocked senders and domains, you will see a list of addresses
That is it. You can now see every email address and domain you have blocked. If the list is long, you can scroll through it or use the search bar at the top.
One thing to note: the web version shows both blocked senders and blocked domains. Domains are blocked with an asterisk like *@spamdomain.com. Senders are individual email addresses.
View Blocked Senders In Outlook 365 Desktop App
If you use the Outlook desktop app that comes with Microsoft 365, the steps are slightly different. Here is how:
- Open the Outlook desktop app on your computer
- Click the Home tab at the top
- In the Delete group, click Junk
- From the dropdown menu, select Junk E-mail Options
- Go to the Blocked Senders tab
You will now see a list of all blocked senders. The desktop app also shows blocked domains and top-level domains (like .xyz or .top). You can add or remove entries directly from this window.
Be careful: the desktop app list is separate from the web version in some cases. If you use both, changes might not sync immediately. Always check the web version for the most up-to-date list.
View Blocked Senders In Outlook 365 Mobile App
On your phone, the Outlook mobile app (iOS or Android) does not have a direct way to view the full blocked senders list. But you can check if a specific sender is blocked:
- Open the Outlook app on your phone
- Tap the Settings gear icon
- Select the email account you want to check
- Scroll down to Blocked senders
- You will see a list of blocked addresses
This list is often limited compared to the web version. For a complete view, I recommend using the web version on your phone’s browser instead.
How To Unblock A Sender In Outlook 365
Once you have viewed the list, you might want to unblock someone. The process is simple and can be done from the same screen.
Unblock In Web Version
- Go to Settings > View all Outlook settings > Mail > Junk email
- Find the sender or domain you want to unblock
- Click the trash can icon next to their name
- Click Save at the top
Unblock In Desktop App
- Open Junk E-mail Options from the Home tab
- Go to the Blocked Senders tab
- Select the entry you want to remove
- Click Remove
- Click OK
After unblocking, emails from that sender will go to your Inbox again. However, if you have also blocked their domain, you need to remove the domain entry too.
How To Add A Sender To The Blocked List
Viewing the list is only half the story. You may also want to add new senders. Here is how:
Add From An Email
- Open an email from the sender you want to block
- Click the three dots (More actions) in the top-right
- Select Block or Mark as junk
- Confirm your choice
Add Manually In Settings
- Go to Settings > Mail > Junk email
- Under Blocked senders and domains, type the email address or domain
- Click the plus icon to add it
- Click Save
You can also block entire domains. For example, typing @spam.com blocks all emails from that domain.
Common Issues When Viewing Blocked Senders
Sometimes you might run into problems. Here are the most common ones and how to fix them.
List Is Empty When You Know You Blocked Someone
This can happen if you are looking at the wrong account. Outlook 365 lets you have multiple email accounts. Make sure you are checking the correct one. Also, check if you are using the web version or the desktop app, as they may not sync.
Blocked Sender Still Sends Emails
If a blocked sender’s email still appears in your Inbox, it could be because:
- You blocked the wrong address (check for typos)
- The sender uses a different email address
- You have a rule that overrides the block
- The email is from a domain you did not block
Cannot Find The Blocked Senders Option
In the web version, the option is under Mail > Junk email. If you cannot find it, try refreshing the page or clearing your browser cache. In the desktop app, the option is under Home > Junk > Junk E-mail Options.
Tips For Managing Your Blocked Senders List
Keeping your blocked senders list clean is important. Here are some practical tips:
- Review the list every few months to remove outdated entries
- Use domain blocking for persistent spammers instead of individual addresses
- Add trusted senders to your Safe Senders list to avoid accidental blocks
- Export your blocked list if you switch email providers
- Never block your own email address or domain
Also, remember that blocking a sender does not delete their past emails. It only prevents future emails from reaching your Inbox. Old emails remain in your Junk Email folder until you delete them manually.
How Blocked Senders Affect Your Inbox
When you block a sender, their emails are automatically moved to the Junk Email folder. They are not deleted, but they are hidden from your main view. This keeps your Inbox clean and reduces distractions.
However, there is a catch. Sometimes legitimate emails end up in Junk Email by mistake. That is why it is a good idea to check your Junk Email folder regularly. If you see an email from a blocked sender that you actually want, you can unblock them and move the email to your Inbox.
Another thing: blocking a sender does not notify them. They will not know you blocked them. Their emails will just disappear into your Junk folder without any bounce-back message.
Viewing Blocked Senders For Multiple Accounts
If you have multiple email accounts in Outlook 365, each account has its own blocked senders list. You need to view them separately. Here is how:
- Switch to the account you want to check
- Go to Settings > Mail > Junk email
- The list shown is for that specific account
Repeat the process for each account. This is important because blocking a sender on one account does not block them on another.
Using Search To Find Blocked Senders
If your blocked senders list is very long, you can use the search feature to find a specific address. In the web version, there is a search bar at the top of the Junk email settings page. Type part of the email address or domain, and the list will filter automatically.
In the desktop app, there is no search bar. You have to scroll through the list manually. To make it easier, sort the list alphabetically by clicking the column header.
What Happens When You Block A Domain
Blocking a domain is more powerful than blocking a single email address. When you block a domain, all emails from that domain are sent to your Junk folder. This includes emails from any address at that domain.
For example, if you block @spam.com, emails from info@spam.com, support@spam.com, and noreply@spam.com are all blocked. This is useful for stopping spam from a specific company or service.
But be careful: blocking a domain can also block legitimate emails. For instance, if you block @newsletter.com, you might miss important updates from a service you use.
How To Export Your Blocked Senders List
Outlook 365 does not have a built-in export feature for blocked senders. However, you can manually copy the list. In the web version, select all entries, copy them, and paste them into a text file. In the desktop app, you can take a screenshot or write them down.
If you need to transfer your blocked list to another email service, you may need to use third-party tools. Always be cautious when using such tools, as they may compromise your privacy.
