Configuring meeting settings would affect parameters related to Teams meetings, such as recording, lobby behavior, or participant roles, and has no bearing on chat message deletion capabilities.

To prevent only a specific group of users (the research department) from deleting chat messages while leaving other users unaffected, the first step is to create a new messaging policy. This custom policy allows for tailored settings regarding chat features, which can then be assigned to the target department.

Modifying the global messaging policy would apply the change to *all* users in the organization, which contradicts the requirement to prevent *only* users in the research department from deleting messages.

Creating a new meeting policy manages settings specifically for Teams meetings, such as who can start a meeting or use certain features during a meeting, and does not control the ability to delete chat messages.
