Guests and Chat in Teams
onethreeone Hey! I believe you've figured this out yourself as you mentioned the delay. Yes, it takes quite some time for the policies to take effect.
For your information I have set up your settings (the ones you've attached) and created an anon account (Gmail). Scheduled a meeting and copied the Teams link into an email and sent it to the newly created anon address (no association at all with my tenant) and this anon user could join the meeting after being let in and participate in a chat.
In other words, as long as the settings are OK you don't have to worry about the guest accounts in AAD.
Hope that helps!
onethreeone Hello, I assume you used the Outlook add-in and sent out the Teams meeting link to all recipients with Outlook the last meeting? I haven't tried this myself but how about doing a "bulk add" to Azure AD? As soon as the invites are accepted they are populated in Azure AD as guests and you can go ahead and schedule a meeting with those users.

ex. add them to a Team and schedule a channel meeting as the limit is 300 for a non-channel meeting.
