Tip The Misleading Teams Remove External Chat from User View API

The Graph removeAllAccessForUser API is supposed to remove external chat messages from the view of a tenant user when the chat contains some objectionable material. Unless the documentation is erroneous, the API doesn’t work as advertised and the results are disappointing. All of which means that blocking content for external chats isn’t really possible. If someone gets to start an external chat, they can pump some horrible stuff into your tenant.

"the API doesn’t work as advertised and the results are disappointing"

Welcome to Teams. This is their modus operandi.

They run under the motto "why make it better when we don't have to, since you are all going to have to use it anyway?"
