Finally posted TeamsTracker code from my DC31 talk. github.com/nyxgeek/teamstrac… It proxies through Microsoft Graph Explorer to make unauthenticated Teams Presence/OOO lookups and logs them to a local db. Requires UUID of Azure account. Takes a CSV export from TeamFiltration, or a list of UUIDs as input. Please don’t use on giant lists like I did with 100k MS employees — there’s a global rate limit to this technique. Let’s share. If you really wanna do some surveillance I’ll be posting technical blogs in the coming weeks detailing how you can set up your own applications in your tenant(s) to do massive Teams monitoring.
