    Those are different functionalities mate, the "external access" settings do not apply to Guest users. To restrict guest access too, switch to the tab above, Guest access: https://admin.teams.microsoft.com/company-wide-settings/guest-configuration

    Hi @Saurabh Singh
    I agree with the above, this is about the settings for guest access. If you want to turn off guest access, you can follow the method below to set up.

    1. Sign into the Microsoft Teams admin center.
    2. Select Users > Guest access.
    3. Set Allow guest access in Teams to Off.
