RE: Business Central for IWs trial license gives unlimited access to Production environment
Thank you everyone for the replies.
Inge - This is BC SaaS and the user does not have any admin rights on the tenant. They are a basic/standard user with an Office 365 E3 license. I'll submit a ticket through our Partner to see what additional insight they or Microsoft can provide on this.
MahGah - Thank you for the reminder about using AD groups on the environment. I added one to our Production environment that includes all the authorized BC users. I was aware of the AD power shell setting that you linked, but it would disable self-service to all applications and our IT department may still want to allow access to those. We may need to use it though at least temporarily until we can remove the IWs licenses from the tenant (if that is possible).
Zhu - Thank you for the reminder, I was aware of that as well but in this case the environment has been up and running since late December and so this wasn't a first-time login.
