Hi @Seifeldin Sabry
Currently, Teams enforces team-wide and organization-wide two-factor authentication, single sign-on through Active Directory, and encryption of data in transit and at rest.
For a detailed introduction, please refer to Security and compliance in Microsoft Teams.
For your considerations on Teams security and privacy issues, please try to configure the following steps:
- Multi-factor authentication (MFA): Log in to the Microsoft Entra admin center and ensure that all users have MFA enabled.
- Access control: Use the Azure portal's access control (IAM) settings to manage resource groups or resources with access permissions and select the users or groups to whom roles are assigned.
- Monitoring and logging: Also in the Azure portal, configure diagnostic settings, enable logging and metrics collection. Set up alert rules to send notifications when abnormal activity is detected.
To add users via email to create a chat, please refer to:
If you still need more detailed guidance, it is recommended that you contact Phone Support, who have more resources to solve your doubts and guide you through the operation.
For the most current support phone number in your country/region, see the global phone numbers list. If your country/region isn't listed, select a neighboring country/region or dial the United States support phone number.
