Office 365 licenses and activated features per user

Ever wondered which user has what license activated and e.g. which specific feature is activated? Recently I was challenged to see who has the Exchange mailbox feature enabled and who not out of the active user base. Due to the huge user-base this would have taken hours to review manually. Using PowerShell for this, connecting to Office 365, exporting the data eventually to a CSV file and filtering it in Microsoft Excel made this way easier.

The challenge here is that Microsoft uses SKU’s – or licenses – that again can have various features enabled or disabled. Let’s say you have a E5 Plan (license) assigned to your user, you still can disabled various features within this plan, e.g. Microsoft Exchange.

If you take a look at the following website, you find a whole list of GUIDs / IDs of all those various features.

In case of the Microsoft Exchange Mailbox feature – we are talking about this GUID: efb87545-963c-4e0d-99df-69c6916d9eb0

Once I had identified the GUID the next step was to grab users from a specific on premise Active Directory OU and query them against Microsoft Azure on the Office 365 environment as for their assigned licenses/features. The results then are collected in a PowerShell object and eventually saved in a defined file name in a CSV format that you easily can filter in Excel afterwards.

Please keep in mind that you will need RSAT tools (PowerShell) and Azure/Office 365 connectivity, rights etc. in order for this to work.
