Previously used Microsoft 365 on a company account. I want to install Microsoft Office to support my documents. When I attempted to purchase Office it sends me to sign into my account. When I attempt to sign in it keep looping back to sign in. I tried different server, did all the forms of sign in and each application for sign in ends up looping back to sign in when I enter codes or password. How can I purchase Office at this point?

    For a home purchase, the purchase and install flow requires signing in with a Microsoft account. If sign-in keeps looping, use these supported paths:

    1. Try the purchase and install from the Microsoft account Services & subscriptions page instead of entering a product key flow.
    2. If a new product key was already purchased, redeem it at www.office.com/setup. After redemption, the product is added to the Microsoft account and future installs should be done by signing in, not by re-entering the key.
    3. If the device was previously connected to a company Microsoft 365 account, disconnect that work account in Windows:
      • Go to Settings > Accounts > Access work or school.
      • If the organization account is listed, select it and choose Disconnect.
      • Restart the PC.
      • When prompted later in apps, choose sign into this app only, not device management.
    4. If Office apps are installed and appear to be tied to the old work account, remove conflicting sign-in data:
      • Close all Office apps.
      • In Windows Settings > Accounts > Access work or school, disconnect unused or conflicting work/school accounts.
      • Restart and try the Microsoft account sign-in again.
    5. If the sign-in loop happens only with a work or school account, that can be caused by an organization security policy blocking sign-in at office.com. In that case, use a personal Microsoft account for a home purchase, not the former company account.
    6. If sign-in still cannot be completed, contact Microsoft support.
