Teams Real Simple with Pictures: Resolving Allow Third Party Cookies in the Teams Web App with Edge

Every Sunday I typically write a blog. Now in order to write that blog I typically use a test tenant set up on the CDX platform at https://demos.microsoft.com. Why? It's what we call a Ring 4 tenant which means that everything within it - all of the functionality in Teams has been released and is generally available. Since my corp tenant is TAP (Ring 3) I can't just take pictures of it or use it in blogs as I may accidently infringe on NDA and the things I am working on with the team at Microsoft. So reviewing the Ring 4 tenant this morning in order to find something to write on, and logging onto the web app via Edge (https://teams.microsoft.com) I was blocked from accessing it which said I needed to allow third party cookies. Ok. Now, this article will focus on a fix for it - not the semantics of whether third party cookies ought to be a prerequisite of the web app experience. Some articles argue that third party cookies need to be on for the browsing experience to be optimal. Others state that third party cookies are a security and privacy risk given they harvest behavioural data. Wherever you fall on this spectrum the fact remains that Teams needs to allow it. I am sure Microsoft will provide an official reason for this in time
