A Microsoft file hosting and synchronization service.
Hello, thank you for reaching out to Microsoft Q&A.
Unfortunately, you cannot transfer the Office 365 subscription from one account to another. So, here are the two options you have now:
- Move the OneDrive files from your Account A to Microsoft Account B, which has the Office 365 subscription. To do that, you will have to download all the files from your Account A to your local computer and then upload them to Account B. (OR)
- Cancel the subscription on Account B and then subscribe on Account A, which already has your OneDrive files.
Please check which option suits you best. Depending on that, you can close the Microsoft account you no longer want to keep.
