How to Stop Uninvited Guests From Joining Your Microsoft Teams Meetings
Your 10am client meeting is underway on Microsoft Teams. The agenda is sensitive - a property dispute, a treatment plan, a financial review. Then someone joins who has no business being there. It happens more often than people realise, and it usually comes down to default settings that nobody has thought to change.
Microsoft Teams is configured out of the box to be convenient, not cautious. That means meeting links can be forwarded, guests can join from the lobby without being checked, and recordings can be accessed by people who were never in the room. For a professional services business handling confidential client information, those defaults create real exposure. Under the NZ Privacy Act 2020, you have an obligation to take reasonable steps to protect the personal information you hold - and that includes how you conduct virtual meetings.
When Teams is set up properly, the difference in your day is simple: meetings start cleanly, only the right people are in the room, and you are not distracted halfway through wondering who that unnamed attendee is. Recordings stay within your organisation. Sensitive conversations stay confidential. You can focus on the client rather than managing access.
The settings that matter most are not hard to change, but they are easy to overlook. Lobby settings control whether external attendees wait for approval before entering. Meeting options let you restrict who can present or record. Link-sharing can be tightened so forwarded invites do not automatically grant access. These are not one-off fixes either - they need to be set as defaults across your organisation, not just adjusted meeting by meeting.
Most business owners are not going to dig into the Microsoft 365 admin centre themselves, nor should they. This is exactly the kind of configuration work that a managed IT support arrangement handles as a matter of course - reviewing your settings, applying sensible defaults, and making sure your tools are working the way your business actually needs them to.
