Download and install Office using Office 365 for business on your PC
If your Office 365 business or education plan includes Office, you can install it after signing in to Office 365 for business in your browser.
Download Office and install Office for Windows
Sign in to Office 365, at http://portal.office.com/OLS/MySoftware.aspx.
If you don't see Office listed, your plan probably doesn't include Office applications. If you know your plan includes Office, you may not have a license assigned, see What Office 365 product or license do I have? If Office is not listed ask your Office 365 administrator to assign a license to you.
On the Office page, select a Language, and then choose Install to install the 32-bit version.
Note To install the 64-bit version, choose 64-bit in the Version section before you choose Install. If you're uncertain, try Choose the 32-bit or 64-bit version of Office for more information.
At the bottom of the screen, select Run.
Follow the prompts and accept the license agreement.
When you see "You're good to go," select All done.
Tip After installing, you can start to use Word, Excel, and the other Office applications. If you can't find the applications, learn how to find the Office applications that you just installed.
Now that you’re done installing Office, set up your email in Outlook.
