Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
Two Microsoft accounts cannot be merged into one, but the extra account can usually be removed from the device or signed out of the app, depending on where it appears.
If the duplicate account is showing in Windows:
- Open Settings > Accounts.
- Select the email account to remove.
- Select Remove Account.
If the duplicate sign-in appears because the same email exists as both a Personal account and a Work or school account:
- This happens when two different Microsoft account types use the same email address.
- To stop the prompt, change the personal Microsoft account primary alias in Manage how you sign in, or contact the organization that owns the work or school account so they remove that address from their directory.
- Those two account types cannot be merged.
If the account is inside OneNote for Windows 10:
- Open OneNote.
- Select Settings and More > Settings > Accounts.
- Select the account to remove.
- Select Sign out.
If the account is a Microsoft account sign-in or recovery issue and removal is blocked:
- Use the Sign-in Helper tool.
- If more help is needed, use Get Help on the web or Get Help in Windows to reach Microsoft support.
- Support agents cannot change account details or send password reset links.
For work or school accounts in Microsoft 365 apps, technical help must come from the organization’s IT helpdesk or admin.
