Microsoft Teams provides a simple method for preventing unwanted communication from a colleague. If you are wondering how to block someone on Teams, the process is straightforward and can be done in just a few clicks. This guide will walk you through every step, from desktop to mobile, ensuring you regain control of your chat environment.
Why You Might Need To Block Someone On Teams
Blocking a user in Microsoft Teams stops them from sending you messages, calling you, or seeing your presence status. This is useful for dealing with spam, harassment, or persistent interruptions from a former coworker. The block is permanent until you manually unblock them, and the other person will not be notified.
How To Block Someone On Teams On Desktop
The desktop app offers the most direct method. Follow these steps to block a user from your chat list or profile.
Method 1: Block From The Chat Window
- Open Microsoft Teams on your Windows or Mac computer.
- Go to the Chat tab on the left sidebar.
- Find the conversation with the person you want to block.
- Click the three dots (More options) next to their name at the top of the chat.
- Select Block from the dropdown menu.
- A confirmation pop-up will appear. Click Block again to confirm.
Method 2: Block From The Profile Card
- Navigate to any message from the user in your chat list.
- Click on their profile picture or avatar to open their profile card.
- In the profile card, click the three dots (More actions) in the top-right corner.
- Choose Block from the list.
- Confirm the action when prompted.
How To Block Someone On Teams On Mobile
The mobile app for iOS and Android works similarly. Here is how to block a user from your smartphone.
Blocking From The Chat List
- Open the Microsoft Teams app on your phone.
- Tap the Chat icon at the bottom of the screen.
- Find the conversation with the person you want to block.
- Tap and hold on the chat thread until a menu appears.
- Select Block from the options.
- Confirm the block by tapping Block again.
Blocking From A Message
- Open the chat with the user.
- Tap on their profile picture at the top of the screen.
- Scroll down to find the Block option.
- Tap Block and confirm.
How To Block Someone On Teams In A Meeting
Blocking someone during a meeting is slightly different. You cannot block a participant directly from the meeting window, but you can remove them and then block them afterward.
- During the meeting, click Show participants (the people icon).
- Hover over the person’s name and click the three dots.
- Select Remove from meeting.
- After the meeting ends, go to your chat list and block them using the steps above.
This ensures they cannot contact you again after the meeting.
How To Block Someone On Teams In A Channel
Blocking a user from a channel conversation is not possible directly. Channels are public or private spaces where multiple people interact. However, you can block the individual user from your personal chats to prevent direct messages.
- Open the channel and find a post from the user.
- Click on their profile picture to open the profile card.
- Click the three dots and select Block.
- Confirm the block.
This stops them from sending you private messages, but they can still see your posts in shared channels.
How To Unblock Someone On Teams
If you change your mind, unblocking is just as easy. Here is how to reverse the block.
- Click your profile picture at the top-right of the Teams window.
- Select Settings from the dropdown.
- Go to the Privacy tab on the left.
- Under Blocked users, you will see a list of all blocked contacts.
- Click the Unblock button next to the person’s name.
- Confirm the action.
Once unblocked, the user can send you messages and calls again. They will not be notified of the change.
What Happens When You Block Someone On Teams
Understanding the effects of blocking helps you decide if it is the right move. Here is what changes:
- Messages: The blocked user cannot send you new messages. Existing messages remain visible to you.
- Calls: They cannot call you via Teams. Any attempt will go to voicemail or fail.
- Presence: Your online status (Available, Busy, etc.) becomes hidden from them.
- Notifications: You will not receive any notifications from that user.
- Channels: They can still see your posts in shared channels, but they cannot @mention you.
The blocked user is not alerted that they have been blocked. They may suspect it if their messages never get a reply, but there is no official notification.
Limitations Of Blocking In Teams
Blocking has a few limitations you should know about. First, it only affects direct communications. If you are in the same organization, the user can still see your name in the company directory. Second, blocking does not remove you from existing group chats. You will need to leave the group chat separately. Third, if you block a user by mistake, you have to manually unblock them—there is no undo option.
How To Block Someone On Teams Using The Web Version
The web version of Teams (accessed through a browser) works almost identically to the desktop app. Here are the steps:
- Go to teams.microsoft.com and sign in.
- Click on Chat in the left sidebar.
- Find the conversation with the user you want to block.
- Click the three dots next to their name at the top of the chat.
- Select Block and confirm.
The web version lacks some advanced privacy settings, but blocking is fully supported.
How To Block Someone On Teams From A Group Chat
Blocking a user from a group chat is possible, but it only affects your direct relationship. Here is how:
- Open the group chat that includes the person.
- Click on their profile picture or name in the participant list.
- Select View profile.
- In the profile card, click the three dots and choose Block.
- Confirm the block.
After blocking, you will still see their messages in the group chat unless you leave the group. To leave the group, click the three dots next to the group name and select Leave group.
How To Block Someone On Teams On An IPhone
The iPhone app follows the same pattern as the Android version. Here is a quick recap for iOS users:
- Open the Teams app on your iPhone.

- Tap More then Block.
- Confirm.
Alternatively, you can open the chat, tap the person’s name at the top, and scroll to find the block option.

Android users have a similar experience. Follow these steps:

If you cannot find the block option, update your Teams app to the latest version from the Google Play Store.
How To Block Someone On Teams Without Them Knowing
As mentioned earlier, Teams does not notify the user when you block them. The block is silent. However, they might notice if they try to send you a message and it fails to deliver. There is no way to hide the block completely if they attempt communication, but the process itself is discreet.
How To Block Someone On Teams Using Keyboard Shortcuts
There are no direct keyboard shortcuts for blocking in Teams. However, you can speed up the process by using the following steps:

- Type the person’s name and press Enter to open their chat.
- Press Alt+Shift+O (Windows) or Option+Shift+O (Mac) to open the profile card.

This is faster than navigating through menus manually.
How To Block Someone On Teams In An Organization
If you are blocking someone within your own company, the process is the same. However, note that your IT administrator can override blocks in some cases. For example, if the user is a manager or has special permissions, they might still be able to contact you through official channels. Check your company’s policy on blocking if you are unsure.
How To Block Someone On Teams After They Leave The Company
When a user leaves your organization, their account becomes inactive. You do not need to block them because they cannot send messages. However, if you want to remove their chat from your list, you can delete the conversation. To do this, click the three dots on the chat and select Delete. This does not block them, but it cleans up your interface.
Common Issues When Blocking On Teams
Sometimes blocking does not work as expected. Here are a few common problems and solutions:
- Block option grayed out: This usually happens if the user is an external guest. Some organizations restrict blocking external users. Contact your IT admin for help.
- Block not saving: Try restarting the Teams app or clearing the cache. Go to Settings > Privacy and check if the user appears in the blocked list.
- Still receiving messages: Ensure you have blocked the correct user. Double-check their name and email address.
- Block option missing: Update Teams to the latest version. Older versions may lack this feature.
How To Block Someone On Teams On A Mac
The Mac version of Teams is identical to the Windows version. Use the same steps: open Chat, click the three dots, and select Block. The only difference is the keyboard shortcuts, which use the Command key instead of Control.

Chromebook users can use the web version of Teams or the Android app. For the web version, follow the steps for the web browser. For the Android app, follow the Android steps above. Both methods work reliably on Chrome OS.
How To Block Someone On Teams Using The Admin Center
If you are an IT administrator, you can block users at the organization level. This is different from personal blocking. To do this:
- Log in to the Microsoft Teams admin center.
- Go to Users and select the user you want to block.
- Under Account, set the sign-in status to Blocked.
- Save the changes.
This prevents the user from accessing Teams entirely. It is a drastic measure and should only be used for security or compliance reasons.

Private channels work like regular channels. You cannot block a user from the channel itself, but you can block them from your personal chats. Follow the profile card method to block them individually.
How To Block Someone On Teams Using The Search Bar
An alternative method is to use the search bar to find the user quickly. Type their name in the search box at the top of Teams, click on their profile, and then block them from the profile card. This is useful if you do not have an active chat with them.
How To Block Someone On Teams And Report Them
If the user is harassing you, consider reporting them to Microsoft. After blocking, you can report the incident. Go to the chat, click the three dots, and select Report a concern. Fill out the form with details. Microsoft will review the report and take action if necessary.
How To Block Someone On Teams On A Shared Computer
If you are using a shared computer, make sure you log out after blocking. Your block settings are tied to your account, not the device. Other users on the same computer will not see your blocked list unless they log in as you.

You can block a user directly from the chat list without opening the conversation. Hover over the chat, click the three dots that appear, and select Block. This saves a click and is faster.
