Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi ChrisCodrington!
I am Shakiru, an independent advisor and a user like you, and I am glad to be helping you out today.
I understand you are a split Microsoft account and you are trying how you want to unify them.
I'm sorry, but did you add an alias email to your Microsoft account? or Did you add a family account to your Microsoft account on your PC? If yes, you may need to remove the new alias or account added.
Kindly let me know how it goes and I will be glad to help further.
Thank you
Kind Regards, Shakiru
