Office 365 domain purpose changing without modifying domain settings

By | June 28, 2016

I’ve come across an interesting bug in the Admin Center Preview portal in-regards to the domain purpose changing without reason. This is further to my recent blog posting: http://realtimeuc.com/2016/06/federation-fails-with-o365/, which required disabling the Skype for Business domain purpose for domains using On-Premises or Third-Party hosted environments without hybrid configured to resolve federation issues.

First you’ll find there isn’t a way in the Admin Center Preview portal to view or modify the domain purpose for Custom domains.

You can use the Azure AD PowerShell to check domain purpose (https://msdn.microsoft.com/en-us/library/jj151815.aspx):
O365DP-06

O365DP-07
As we can see my custom domain is only enabled for Exchange Online and Intune. Note: At this time you can’t change the domain purpose/capabilities using PowerShell.

Now to the bug…. While using the Admin Center Preview portal, go under Settings, Domains, select your Custom domain, click DNS Management and use any option (Next/Back/Exit), you now have enabled all the domain purpose items without notification or warning.

O365DP-08
O365DP-09

At this point the only way to modify the domain purpose is to revert back to the old Admin portal and follow the steps outlined in http://realtimeuc.com/2016/06/federation-fails-with-o365/:

O365DP-13

Status:

Reported to Office 365 support.

    Now that the Old Admin center if fully De-commissioned is there a way to achieve this in New Admin center or Powershell.
