Provisioning a team with hundreds of guest users

Question

I was wondering how would I go about provisioning a team that will have hundreds of guest users?

I looked at PowerShell and School Data Sync, but it's only possible to add members within the organization. Is there a way to add about 13.000 guests (in an organisation that has 250 employees), without having to add them individually? It's an EDU tenant.

We would split 13.000 users to multiple teams, so 10k limit will not be reached per team.

Thanks

Answer 1

Well there are two ways to do this. One which you already mentioned - PowerShell - You can add people outside your organization(Guests). Adding guests is a two step process. 1st you need to invite user, 2nd add him to the team. Check this documentation for how to add the guest and how to add bulk users using PowerShell script. And second option is to use api.

Answer 2

As per my knowledge, you have to add guest users in azure active directory. If you need some special features like MFA then for guest users you can add up to 5 guest users for 1 license otherwise there are no restrictions. In the past I created 132 guest users for my azure account.

Answer 3

Yes, it is possible to add guest users in your Teams organization.

1. Add guest users as mail contacts in your exchange organization
2. Add the contacts in to Teams You can find a short video tutorial prepared in my blog explaining this in the link shown below: If you are looking for the solution which I explain in my blog, I can help out further in preparing PowerShell script to add all users by PowerShell cmdlet
