Microsoft has clarified that the Teams Pro service plan is being added to Office 365 enterprise and Microsoft 365 business standard and premium licenses. Tenant admins don't have to do anything to add the new service plan as Microsoft will do this for them. Teams Pro adds the ability to differentiate product features across different types of user licenses. Teams Pro does not replace the Teams Advanced Communications add-on, but it needs an overhaul too.
Microsoft posted an announcement about a new Teams Pro license last week and promptly confused everyone. The clarification posted a few days later didn't help too much either. Here's what we know about Teams Pro and how we think this new licensing capability will be used.
