Licensing in Office 365 is no more an easy topic to discuss. Microsoft is trying to provide customers with highly flexible options. The result is that there are many license types which an administrator must know to find the appropriate licences for his company. Within this article I’ll briefly describe the currently available plans to make it easier to understand what’s available and what fits best. It is important to understand that these plans can change any time and reflect the status of October 2016.
