Office 365 Essentials and Joining Azure Active Directory

Occasional Visitor

We have recently migrated our company 12 sites, 100+ users over to Office 365.


We are using Office 365 Essentials licenses.


We want to be able to connect devices (Desktops and Laptops) to Azure Active Directory in order to get company wide single sign on. 


When following the following steps however the Joining process fails.


  1. Goto Windows Settings
  2. Click "Accounts"
  3. Click "Access work or school"
  4. Click "Connect"
  5. Click "Join this device to Azure Active Directory"
  6. Enter correct login/password

The following error occurs.

Something went wrong.


It looks like we can't connect to the URL for your organisation's MDM terms of use. Try again, or contact you system administrator with the problem information from this page.


Additional problem information:


Error: invalid_client

Error subcode:

Description: failed%20to%20authenticate%20user


Can anyone please advise how to get this functionally working.


Essentially we want to create a new user through Office 365 Admin, apply Office 365 Essentials license and then be able to connect a Desktop or Laptop so that anyone in the organisation with valid credentials can log onto that device.


Thanks in advance for any advice or assistance given.

You need Azure AD Premium license for this, this is not included in O365 Essentials.
