If You Cannot Add a Student
Only users who already belong to the organization that the group belongs to can be added to the group. If the target student does not yet belong to the organization, first add them to the organization by inviting members to the organization.
Notes
You can enter multiple email addresses at once.
If you re-enter an existing group member, it is treated as a permission review rather than a duplicate addition.
You can also remove group members in bulk by entering multiple email addresses. For details, see Remove members in bulk.
