A Microsoft file hosting and synchronization service.
Hi Wendy,
Log into any Microsoft account you may have on this link.
https://account.microsoft.com/services/
Do you find two separate Microsoft 365 subscriptions on one account or are the subscriptions on two different Microsoft accounts?
If you find the Basic and Personal subscriptions on the same Microsoft account, you can cancel the Microsoft 365 Basic subscription, if your OneDrive storage does not exceed the 1TB of OneDrive storage you get with the Microsoft 365 Personal subscription.
If the Basic subscription is on a separate Microsoft account, it is not possible to merge the two Microsoft accounts, you would need to download any files on that Microsoft account to your PC to ensure you have a safe local copy of the files before cancelling the Basic subscription, and also open OneDrive settings from its cloud icon on your taskbar to ensure you are using the Microsoft account with the Microsoft 365 Personal subscription to sync your files online.
