One of my customer informed me that why is his Office 365 Groups got big? I went in and help the customer to have a look at it together. I notice the email addresses are different and not normal looking kind. So I was thinking and checking the utilization dashboard and asked customer “Is Teams being launch?”. Answered “In the process”. Hurried that I had to run a disable Teams creation script and to prevent unnecessary Office 365 Groups created.
I saw Office 365 Groups with naming like “Jom Makan-Makan”, “I hate this Job”, “Boss Convo”, “What is Life” and etc.. This is why you should disable Teams creation capability to tenant wide, when you first deployed Office 365.
So what is the right way?
- Disable Teams creation tenant wide
- Create a security group
- Include only champions or Head of Departments as privileged owners to create Teams / Office 365 groups.
