2023 has been one wild year. The divestiture and merger of the business I work for. It's subsequent rebrand. The last few weeks its been all about expansion and the rollout into Switzerland. I've been over in Ireland. I've been doing things out in the UAE. Now all of these things - all up - have gone well. Despite many long days and a few pressure cooker situations it's been generally excellent and a very exciting experience; one of those intense and fascinating periods where you need to bring your A game and step up to the challange of it. But for the first time since I have been in the Microsoft Tech Community - since around the start of 2018, the sheer load and the scale of realignment has meant I have struggled to get to the community. The blogs. The events. All the rest of it. I completely missed Build. I completely missed Commsverse. I simply couldn't get to them. And whilst I managed to squeeze out a bit on Collaborative Security in May; the new functionalities such as Attack Simulation, End User Reporting and ZAP, I've had people ask - where have you been? Are you ok? The answer is yes! I am happy that corp work is almost to a sustainable level, and that I can start to engage with the community again. And so I am going to pick up with a small, security related functionality in Teams meetings which I noticed has now appeared in the Teams Admin Centre (TAC) which is to block anonymous users read access in a Meeting Chat. More succinctly 'Microsoft Teams IT Admins will be able to block anonymous users from accessing the chat in internally hosted meetings by disabling their read access on top of the existing disabled write access'. In other words, anonymous users will have neither read or write meeting chat access meaning they won't see the chat. Why is this important? An anonymous user is a user who joins a meeting via a link. The user isn't logged in with their Microsoft account or their organization’s account. This could, literally be anyone who has received, or managed to get their hands on the link to the meeting who isn't strictly authorised to be there. And if we permit anonymous users - which some orgs need to do, then it is good that the chat can be controlled in such a manner that these users can't scrape/exfiltrate information - particularly sensitive information out the chat. All set?
