One of the frustrating things about Microsoft 365 Business was that it didn’t include the full Azure AD P1 feature set. It had about 80%. This unfortunately created a lot of confusion for people to know exactly was and was not included. For example, Dynamic Groups WAS part of Azure AD P1 but NOT part of Microsoft 365 Business.
That was until now! Per the above Message Center notification, Microsoft 365 Business will receive the full Azure AD P1 from April 2020! Seems like all of us (including Alex Fields, got our Christmas wish)
Thanks Microsoft, that’s going to make things much easier.
