Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi BigBadDom,
You have a Microsoft account set up using the same address as your work email?
You need to log into https://account.live.com/names/Manage and add an outlook.com address to your profile and set it as primary.
Do you have any subscriptions or purchases linked to your Microsoft account (on the services and subscriptions page)? If so, don't remove the work address from the account. You can remove the ability to sign in using the address - using the link at the bottom of the page for sign in preferences.
