Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
The first iteration of Office365 was BPOS (Business Productivity Online Suite) many years ago. Some of these features were built into the product then, accessed via Exchange Admin. It included features like device wipe. Over time these features got enhanced but remained in Exchange Admin.
However, Microsoft also has a more advanced MDM system in Intunes.
Later versions of Office365 came with a Lite version of this MDM. There are more granular features, like selective wipe, but it required a user registering the device and downloading a client on their phones. This is parked under Security & Compliance -> Data Loss Prevention -> Device Management / Device Security Policies.
You can compare the two approaches and see which one works best for you.
