What happens if I add another Office 365 for home subscription to my account?

For home or personal use, you can choose from three Office 365 subscriptions: Office 365 Home, Office 365 Personal, and Office 365 University. However, your Microsoft account — the email address and password you use to install Office — can have only one active Office 365 subscription.

If you add the same Office 365 subscription to your Microsoft account, you’ll have the same subscription benefits (same number of Office 365 devices you can sign in to and the same amount of Skype minutes and OneDrive storage) as before. You're extending the amount of time for that subscription, not increasing the number of Office 365 devices you can sign in to or amount of online storage you get. You can extend the duration of an Office 365 subscription for up to 5 years.

For example, if you use an Office 365 Personal product key to renew, and you currently have an Office 365 Home subscription, you'll be offered a choice to stay with Office 365 Home subscription and receive less than a year of subscription benefits, since Office 365 Home costs more, or you can switch to Office 365 Personal.

What do you want to do?

If you already have an Office 365 Home or Office 365 Personal subscription, the table below summarizes your options when you switch from one subscription to the other. To see full subscription details, like how many Office 365 devices you can sign in to or the number of Skype minutes, see Office 365 subscriptions.

Whether you stay with the same subscription or switch to a different subscription, your online storage capacity per user doesn’t change. For example, if you have only one user on the subscription, you’ll have 1 terabyte of storage, but if you have Office 365 Home and share with five other people, you get a total of 6 terabytes of storage.

I want to extend my subscription

When you add an Office 365 subscription to an account that already has an Office 365 subscription, any remaining time from your current subscription is added to the new one. For example, if you have 6 months left on your current Office 365 Home subscription and you add a new yearly Office 365 Home subscription to your account, we’ll extend it to 18 months.

If you try to add too many subscriptions at once to the same account, you’ll get a Redemption Failed error because you can’t exceed the 5-year maximum.

In most cases, adding a different subscription to your Microsoft account automatically switches you to the new subscription. But, when you apply an Office 365 Personal product key to an account that currently has an Office 365 Home subscription, you’ll be given the choice to stay with Office 365 Home or convert the subscription to Office 365 Personal. After you switch, your subscription benefits will be updated. To learn more, see the "Managing your Office 365 subscription" section in Office 365 frequently asked questions. To learn how to switch subscriptions, see Switch to a different Office 365 for home subscription.

Important: If you accidently switch your Office 365 Personal, Home, or University subscription, contact Account and billing support.

You can use the free offer in any of these ways:

  • Redeem the offer now and choose to stay with Office 365 Home. This will add an additional 9 months to your subscription.

  • Redeem the offer now and switch your Office 365 Home subscription to Office 365 Personal. This will add an additional 12 months to your subscription.

  • Redeem the offer now using a different Microsoft account.

  • If you want to stay with your current subscription for now, you can wait until your subscription expires and then redeem the free offer for Office 365 Personal.

If you have an existing Office 365 Home subscription and redeem the offer for a free year of Office 365 Personal, you’ll be asked if you want to convert your existing subscription to Office 365 Personal or stay with Office 365 Home. If you convert to Office 365 Personal, you won’t be able to share your subscription.

To learn how to redeem the free offer and add it to your current subscription, see Switch from Office 365 Home using a product key.
