Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Following a Unified Support call with Microsoft I have an answer (of sorts) ... might not be everyone's answer but applied to our tenancy / our scenario. Unified Support referred us to the following notification: End of support guidance for Windows Information Protection
If you read through the article there's an important bit in the middle:
.. as follows:
- November 1^^(or soon after) we will restrict creating new WIP ‘without enrollment’ policies from the Microsoft Intune admin center.
- Starting in December 2022, we will begin deregistration for devices utilizing WIP ‘without enrollment’. Refer to the Message Center for when this will occur for your organization. We plan on completing the deregistration in the following order:
- Devices receiving no effective policies.
- Devices receiving ‘disable WIP’ Policy.
- Devices receiving policy to configure WIP.
Important: Once the device is unregistered, users may see a notification indicating an account has been removed, “mddprov account has removed your workplace account…from your device.” You can safely disregard this message.
Hopefully this explains some of the craziness and also why Microsoft are not treating this as a problem (it's expected behaviour).
