    Microsoft consumer and Microsoft 365 accounts cannot be merged. Each account (identity, mailbox, purchases, subscriptions, OneDrive, Xbox profile, etc.) remains permanently separate.

    To consolidate usage around one account:

    1. Choose which account will be kept as the primary going forward.
    2. Manually move data and services where possible:
      • Email: forward or export/import mail between mailboxes.
      • Contacts/calendar: export from old accounts and import into the primary.
      • Files: download from old OneDrive locations and upload to the primary OneDrive.
      • Subscriptions/services: sign in to each service and, where supported, cancel under the old account and re-purchase or reassign under the primary account.
    3. Update sign-in everywhere to use the primary account (Windows sign-in, Office apps, Xbox, mobile apps, etc.).
    4. When certain nothing more is needed from an old account, close or stop using it. Note that some aliases (for example @outlook.com, @hotmail.com) cannot be reused on another Microsoft account once removed.

    If the scenario involves organizational/partner or service accounts (for example, Partner Center, Microsoft Purview, Dynamics/Power Platform, or Dynamics GP), those have their own merge/combine features, but they do not merge Microsoft identities either:

    • Partner Center: partner organizations can merge Partner Center accounts for centralized management, but tenant/user boundaries remain separate and the merge cannot be reversed.
    • Microsoft Purview: a classic Purview account can be merged into a tenant-level Purview account as a domain. This is a one-time copy of data; the secondary account still exists until deactivated or deleted.
    • Power Platform (Dataverse): individual records (Accounts, Contacts, Leads) can be merged to remove duplicates, but this is data-level, not account/identity-level.
    • Dynamics GP: financial accounts can be combined using Account Combiner, again only at the application data level.

    There is no supported way to technically merge three Microsoft accounts into one single account; only manual consolidation and service-specific merges are possible.
