Org-Wide Team in Tenant with A5 Licenses?

Tobiasistschonvergeben 

When an organization-wide team is created, all Global Administrators and Teams Administrators are added as team owners and all active users are added as team members. Team members can't leave an organization-wide team, but team owners can manually add or remove users if needed. When Teams automatically adds or removes someone, a notification is sent to the General channel.

Unlicensed users are also added to the team. The first time an unlicensed user signs in to Teams, they're assigned a Microsoft Teams Exploratory license. To learn more about the Exploratory license, check out Manage the Microsoft Teams Exploratory license.

The following types of accounts won't be added to your organization-wide team:

• Accounts that are blocked from sign-in
• Guests
• Resource or service accounts (for example, accounts associated with auto attendants and call queues)
• Room or equipment accounts
• Accounts backed by a shared mailbox

How big is your organisation? If you have over 10,000 licensed members you won’t be able to create org-wide teams.

There’s also a limit of  5 org-wide teams per tenant.
