I am trying to add 2 guests to a Microsoft Teams channel and am not being allowed to.

Do you enable guest access in Teams?

Based on my research, you must be a team owner to add a guest in Teams. Before guests can join a team, an admin must enable guest access in Teams.

To set Teams guest access settings:

1. Log in to the Microsoft 365 admin center at https://admin.microsoft.com.
2. In the left navigation pane select Users > Guest access.
3. Ensure that Guest access is set to On.

If you want to add people outside your org to a shared channel, admins must enable B2B direct connect.

Azure AD B2B direct connect is disabled by default. To enable collaboration in shared channels with people from other organizations, you must:

1. Add an organization.
2. Configure inbound settings for the organization to allow users from the organization to be invited to your shared channels.
3. Configure outbound settings for the organization to allow your users to be invited to the other organization's shared channels.
