Downloading & installing Microsoft Office

You’ll need a valid Office license before you download & install. If you don’t have one, see Purchasing Microsoft Office first.

Logging into Microsoft Office to download & share

For iPhone, iPad or iPod touch, see this page and tap the links for the apps you need to install.

  1. On the computer where you want to install Office, open a browser and go to Or if you were invited by email to Office, click the link in the email to sign in.
  2. Click Sign in at the upper-right corner. Choose Home or Work, then enter your Microsoft account and password. (If you’re using an invitation email, use the email address where the invitation was sent.) Home users can create a new Microsoft account if you don’t have one.
  3. Click My Account at the top of the page.
  4. To install Office, click Install. Don’t see this? Click My Account at the top of the page first.
  5. OPTIONAL: To share an Office 365 Home subscription with others, click Share and invite someone by their email address. Each user will sign in with their own account when they install Office on their computer. They also use the account to unlock editing capabilities in Office for iPhone & iPad, and Microsoft OneDrive. (Only Office 365 Home subscriptions are shared from this page.)
  6. After Office downloads, open the installer package. If it doesn’t appear automatically, look in your downloads.

  8. Look for Microsoft Office apps in the Launchpad, Applications folder or start page. You can drag them to the dock or pin them to the task bar.
  9. You need to activate Microsoft Office before you can save or print documents.

Updating Microsoft Office

After you’ve installed Microsoft Office, it periodically checks for updates & bug fixes. You can also do this manually.

  1. Open a Microsoft app, like Word, Excel or PowerPoint.
  2. Click the Help menu and Check for Updates.
  3. You can set how frequently Microsoft checks for updates. Monthly is probably often enough. If we’re updating your organization’s Macs, leave it set to Manually.
  4. Click Check for Updates. You’ll see a list of all available updates. Typically, you’ll install all updates.
  5. Click Install. You can work while software is downloaded. You’ll have to quit your Microsoft apps before it actually installs.
