Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Hi Carolyn,
As per checking, Microsoft accounts are treated as separate entities, so subscriptions and data cannot be merged between different accounts. Therefore, if you renewed Microsoft 365 under a new email address, the system will not automatically recognize that it replaces your old account, which is why you still see renewal notices tied to the original subscription.
On this case, the best step to proceed is to confirm which account you want to use going forward, on whether the one where the active subscription is now registered and then manually move your files from the old account to the new one to ensures the data is preserved and accessible under the account that holds the valid subscription.
Because there is no way to merge accounts or transfer subscriptions directly, so manual moving files is the only supported method to consolidate your data.
