How Microsoft Teams QR code works
Create a Microsoft Teams QR code from the full meeting link, then test browser or app opening, guest access and lobby behavior before sharing.
What the QR code contains
Copy the complete meeting link from the Teams calendar details or invitation. It may be much longer than the visible Join meeting text; store the full HTTPS URL rather than a meeting title or channel address.
Where it works
The link can open Teams on the web or the installed desktop or mobile app. Browser support, anonymous joining, sign-in, available features, and lobby placement depend on the device and organizer policies.
Limits to check
Teams links do not have one universal lifetime. Expiry varies for scheduled, recurring, and Meet now meetings, and joining or updating some meetings can extend it. A QR code cannot bypass the lobby.
