MFA on specific Microsoft Teams meetings for external

Hi MohFarah,

in this specific scenario you've described, where a healthcare center conducts sensitive Teams meetings with external participants, and there is a concern about applying Multi-Factor Authentication (MFA) specifically for external participants, the technical options are limited within the standard Microsoft Teams settings.

Here's how you can reolsve your scenario:

1. Conditional Access for MFA: You can use Conditional Access policies to enforce MFA for specific groups of users or all users. However, this control is generally applied at the user level and not at the meeting level. So, while you can require MFA for all users or specific groups, it will apply to their overall access to Microsoft Teams, not just to individual meetings.
   
   This means that if MFA is enforced for external participants, it would apply to all interactions within Microsoft Teams, not just specific meetings.
   
   

2. Meeting Policies: Within Microsoft Teams, you can control certain aspects of meetings using meeting policies. While you can restrict the ability to record meetings or present in meetings, you can't use meeting policies to selectively enforce MFA for external participants in specific meetings. Meeting policies are generally applied globally or to specific users or groups.
