ad-hoc Teams meetings with external users

Ok let's help!

1.) In the Teams Admin Centre go into Meeting Policy and ensure that Anonymous users can join a meeting is on

2.) In the Teams Admin Centre ensure that external user access is enabled in org wide settings
3.) Create the meeting
4.) In the meeting booking go into meeting settings and ensure that everyone can bypass the lobby

Should be a nice friction free meeting when they click on join teams in the meeting invitation. They don't have to be guests: guests should only be created when you want people to work in your team in your tenant

Let me know how you get on. Note; the policy above (if it is turned off) could take up to 24 hours to propagate

Hope that answers your question

Best, Chris
