How do I merge my personal and work Microsoft accounts?

Personal Microsoft accounts and Office 365 work or school accounts cannot be merged, but they can be used side by side. 

Select from the options below for the best way to use personal and work or school account together.

You can use OneDrive to sync both your work or school files and personal files to your computer. You can work with files directly on your computer and access them even when you're offline. Whenever you're online, any changes that you or others make will sync automatically.

Tips: 

  • You can also use this approach to add your personal OneDrive to an existing OneDrive for Business account.

  • Your personal and work or school OneDrive storage allowances remain separate.

When someone shares a folder and gives you edit permissions to it, add the shared folder to your own OneDrive to make it easier to edit and work with the folder and its contents. If you sync the folder to your Windows or Mac computers running the OneDrive app, you can work with the folder offline.

Tip: Shared folders added to your OneDrive do not use any of your OneDrive storage space. They only count against the folder owner's storage space.

If you want to use a new email address with your existing Outlook.com account, follow the instructions in this article to create an alias. This will give you an additional email address which uses the same inbox, contact list, and account settings as your primary email address. You can choose which email address to send mail from, and you can sign in to your Outlook.com account with any of your aliases—they all use the same password.

Tips: 

  • You cannot add an alias that is already associated with another Microsoft account. 

  • You can't add an email address that's already associated with a work or school account as an alias. See below for more details.

  • An alias or email address can only contain letters, numbers, dot (.), underscore (_) or dash/hyphen (-). Spaces and other special characters are not allowed.
