Microsoft personal and work/school accounts cannot be combined or merged. There is no way to move all data, purchases, or settings into a single Microsoft account.
For personal Microsoft accounts:
- Existing Microsoft personal accounts cannot be linked, merged, or combined.
- Game progress, gamertag, purchases, and balances cannot be transferred from one personal account to another.
- Accounts can only be used side by side. For example:
- Add multiple accounts to Outlook so email from different accounts can be managed in one place.
- Use OneDrive for work or school and OneDrive for home separately; storage is separate, but files can be copied or dragged between them.
- Share a Microsoft 365 Family subscription with other accounts instead of merging them.
- Use Family groups, multiple Windows accounts on a PC, Xbox profiles, or Microsoft Edge profiles to work with multiple accounts without merging.
For work/school vs personal accounts:
- A work or school account cannot be combined or merged with a Microsoft personal account.
- These accounts can also only be used side by side (for example, both added to Outlook or OneDrive, or used in separate Edge profiles).
If duplicate accounts exist, the practical options are:
- Decide which account to keep using going forward.
- Use supported side-by-side options (Outlook, OneDrive, Edge profiles, Family sharing, etc.) to access content from both.
- If one account is no longer needed and has no important data or purchases, it can be closed following Microsoft’s account closure process (not a merge; data in that account is lost once closure completes).
