Hi @이경아
Do you want to disable chat for some members of your organization?
You can contact your organization admin to add a messaging policy in the Teams admin center to disable chat:
1.Open the Microsoft Admin Center Page.
2.On the menu to the left, you will see all the available settings. Click on Messaging Policies.
3.Click on Add to create a new messaging Policy.
4.Name the new policy. It would be better to give it a descriptive name so you can easily assign it later.
5.You will see a set of toggles that will allow you to pick and choose the specific settings for this policy. As you want to remove chat, find the Chat toggle, then turn it off.
6.Once you are done choosing the settings, click on Save.
Now that you have a messaging policy that prevents users from using the chat function, all that’s left is to assign members to that policy. To do this, follow these instructions:
1.On your Microsoft Teams Admin Center Page window, click on the Messaging Policies option on the menu to the left.
2.Click on your newly created policy.
3.From the menu just above the policies, click on Manage Users.
4.A popup window will appear that allows you to choose the users that will be following this messaging policy. Type in the name of a member, then click on Add.
5.Click on Apply. Users that are part of this messaging policy will now be barred from using chat.
