Here's how to set up your Office 365 Business Premium subscription: set up email with your business name, download and install Office on your PC or Mac, and set up Office apps on your phones and tablets.

These steps are for businesses and nonprofits that want to start with the basic Office 365 Business Premium plan that's set up with the default features.

1. Add your users and domain to Office 365   

When you signed up for Office 365, you got a user ID that includes an “” domain. In this step, you can add your own domain so your user ID and email are personalized for your business, like Domain setup can be confusing, but we’ll guide you through it step by step. What's a domain?

We'll also show you how to quickly create accounts and email addresses for other people in your business so they can use Office 365. If you're the only one using Office 365 in your business, you can skip adding accounts in the wizard. After initial setup, you can add or delete users from your subscription any time.


2. Download and install Office on your Mac, PC, and Mobile   

Once you've created accounts for other people in your business, you and your team members will be able to install the full desktop version of Office (Word, Excel, Outlook, etc.) on your Mac or PC. Each person can install Office on up to 5 PCs or Macs.
