    Dear @(3H09) Lau Hin Ting Ethan

    I understand your concern about suspicious activity in Microsoft Teams. If you suspect that someone else has accessed your Microsoft 365 account, I recommend checking the sign-in history first.

    For a work or school account:

    1. Go to https://mysignins.microsoft.com and sign in.
    2. Select Recent Activity.
    3. Review the sign-ins and check the date/time, location, device, browser, application, and sign-in status.
    4. If you see a successful sign-in that you do not recognize, change your password immediately and review your MFA/security methods. Microsoft recommends doing this if you find unfamiliar sign-in activity. Please refer to this document: View your work or school account sign-in activity from My Sign-ins

    If you are a Microsoft 365 administrator, you can also check Microsoft Admin Center > Microsoft Entra admin center > Entra ID > Monitoring & health > Sign-in logs. These logs provide more detailed information about the user, application, IP/location, device, and authentication method. Please refer to this document: Learn about the sign-in log activity details

    Please note that an unfamiliar location does not always mean an account was compromised. VPNs, mobile networks, and other network routing can make the reported location different from your actual location.

    If the sign-in history shows an unfamiliar successful sign-in, I would recommend changing the password and reviewing your MFA/security information before continuing to use Teams.

    For a work or school Teams account, recent sign-in activity can be checked from My Sign-ins:

    1. Sign in to the My Account page with the work or school account.
    2. Select Recent Activity from the left navigation pane.
    3. Expand each sign-in item and review the details.

    Check whether the sign-ins match the expected browser, operating system, app, and location. Location alone can be misleading because mobile networks can route traffic through other places.

    If an entry looks unfamiliar:

    1. Change the password immediately.
    2. Go to Security info and update security settings.
    3. If there are unsuccessful sign-ins, register for two-step verification / multi-factor authentication. If a sign-in shows "Additional verification failed, invalid code", change the password because the primary password may already be known.

    On Android, recent account activity can also be viewed in the Microsoft Authenticator app by opening the work or school account and selecting Recent account activity.

    If the goal is to identify exactly who accessed the Teams account, a regular user cannot view full tenant sign-in logs. A Microsoft 365 or Entra ID admin can check sign-in logs and audit logs for the account and the incident time window.
