If you see a screen asking "Which account do you want to use?" when you sign in, it means you have two accounts with Microsoft that use the same email address:
- A “Work or school” account, which was probably created by your IT department
- A “personal” account, which you probably created yourself
If you’re tired of seeing this prompt, you can change the email address that you use to sign in to your personal account. Doing this changes the way you sign in to your account, but it won’t affect any of the data associated with it.
Changing the email address of your personal account can help simplify your interactions with Microsoft applications, products, and services by separating your work activities from your personal activities. However, this process can't be undone, and in some scenarios, it may not be helpful.
- You use a Windows phone running Windows 8. You will have to reset your phone.
- You are part of our Xbox Developer community. You could lose access to some developer tools.
- Your Visual Studio or MSDN subscriptions are linked to your Microsoft account.
To change the email address of your personal Microsoft account, follow these steps:
- Sign in to the Your Info page of your Microsoft account.
- Select Manage how you sign in to Microsoft.
- Look under the Account alias section.
- If you already have a personal email address listed there, you can skip this step.
- If your work or school email address is the only one listed, enter your personal email address, or get a new one from Microsoft, and select Add email or Add phone number.
- If your personal email address does not have (primary alias) listed next to it, select Make primary to set it as your primary alias.
- Select Remove next to your work email address to remove it from your account.
Going forward, you’ll sign in to your personal Microsoft account with your personal email address. You might need to sign in again to some apps and Windows devices.
You can also add aliases to your Microsoft account to change how you sign in and how you show up to recipients. For more info, see Manage aliases for your Microsoft account.
What's a Microsoft account?
If you've ever used Outlook.com, Hotmail, Office 365, OneDrive, Skype, Xbox, or Windows, the email address and password you use for any of those services is your Microsoft account. This account gives you access to these and other apps and tools across multiple Windows 10 devices. As described at the beginning of this article, you may have both a Microsoft personal account and a work or school account.
Your personal account is the basis for your long-term personal relationship with Microsoft. This is the account you’ll use continuously, regardless of who your employer is over time. If your Windows 10 login screen shows an email address today, or you have an Outlook.com email address, you're probably logging in with a Microsoft personal account.
On the other hand, your Microsoft work or school account is tied to your company. If you change jobs or change your business (or school), this account will change. The work or school account includes Office 365 business mailboxes, Azure cloud services, SharePoint, and more. If you have a business Office 365 email address, it’s part of your work or school account.
