How to Block External Users on Microsoft Teams
Blocking external users in Microsoft Teams is straightforward. Follow these steps:
- Open Microsoft Teams: Launch the app and go to the "Chat" tab.
- Find the External User: Search for the user you want to block. You can find their name in your chat list or use the search bar.
- Open the Chat: Click on the chat with the external user.
- Block the User:
- Desktop: Click on their profile picture then select "Block contact".

- Mobile: Tap on their profile picture, select "More options", then choose "Block".
Differences Between Blocked Contacts (External and Internal)
Blocking external and internal contacts has different implications:
- External Contacts:
- Blocked users cannot send you messages or see your status.
- Useful for blocking users not within your organization.
- Internal Contacts:
- Blocking isn’t supported for internal contacts in the same organization.
- Instead, you can "Hide" or "Mute" conversations to reduce disruptions.
Limitations and Alternatives if Blocking Isn't Possible
Blocking might not always be possible or the best solution. Here are some limitations and alternatives:
- Limitations:
- Cannot block internal contacts.
- Blocking might not prevent all forms of interaction if the blocked person is persistent.
- Alternatives:
- Hide Conversations: Removes the chat from your view until a new message is sent.
- Mute Notifications: Silences notifications from a specific chat, reducing interruptions.
- How to Hide:
- Click on the chat, select "More options", then "Hide".
- How to Mute:
- Click on the chat, select "More options", then "Mute".
Using these features can help manage your interactions and maintain focus during work hours.
