Microsoft Teams Guest User Limits & Licensing

[taraerin]

I am planning to use Teams as the hub for an online mastermind community and various classes I am hosting online, and need the ability to add about 10 to 20 guest users to various Microsoft Teams.

Based on what I've read so far (e.g. https://techcommunity.microsoft.com/t5/Office-365-Groups/Licensing-for-external-guests-in-Office-365...), it appears that there is currently no set limit on how many guest accounts I can create within Microsoft Teams. 

• Is this correct?
• If not, what is the limit, and how can a purchase additional guest licenses if needed?

There is no hard limit, and there is no Guest user license. However, Microsoft "reports on" (and might "enforce") a 1:5 ration between the number of licensed users in the tenant and guest users, as detailed for example here: https://docs.microsoft.com/en-us/microsoftteams/guest-access-checklist#if-your-guests-are-seeing-lic...

Thank you Vasil - this is a very helpful response. I definitely have enough licensed users to run my program without exceeding a 1:5 use/:guest ratio, so I guess I can just cross the bridge of additional users/guests when I come to it.
