Office 365 is the flagship office software from Microsoft and it is undeniable that this is the best office suite available anywhere in the world today.

There are free office products such as the LibreOffice suite or even Google Docs but the industry standard consists of Word, Excel, Powerpoint and Outlook. Couple these applications with Access and Notes and you have one truly outstanding set of tools.

In the past Microsoft Office has been a bit pricey but in recent years Microsoft has released a subscription service and renamed the product to Office 365.

For one small monthly payment or indeed an annual fee you can get the latest office suite installed to your computer.

As the sign up process can be a little confusing this guide has been created to show you how to sign up, download and install Office 365.

Choose the Office Subscription That Suits You

Choose A Microsoft Product


In order to use Office 365 you need to make sure your device has the correct requirements.

Essentially for home use you will need:

  • a minimum of 2 gigabytes of RAM
  • a 1 ghz processor with SSE2 instruction set
  • 3 gigabytes hard disk space
  • Windows 7 or higher

These instructions will therefore work on computers running Windows 7 and up.

Subscription Options

The first step in the process is to visit

There are two options available:

  • For home
  • For business

Click on the relevant option for your needs.

If you choose the home button then you will see a list of three options:

  1. Office 365 home
  2. Office 365 personal
  3. Office home and student

The Office 365 home option comes with a Try Now button as well as a Buy Now button whereas the other two options only have the Buy Now option.

Office 365 home allows installation on 5 computers whereas Office 365 personal only allows the installation on 1. The student version has fewer tools available.

If you choose the business button then you will see this list of options:

  1. Office 365 Business
  2. Office 365 Business Premium
  3. Office 365 Business Essentials

Office 365 Business has the full office suite and cloud storage but does not come with email. Office 365 Business Premium has the full office suite, cloud storage, business email and other services. The essentials package has the business email but no office suite.

The Sign up Process

Buy Microsoft Office


If you click on the Buy Now button you will be taken to a shopping cart showing the product you have selected,

When you click Next or if you chose the Try Now button you will be asked to sign in with your Microsoft account. If you do not have a Microsoft Account you can click the Create One link.

If you need to create a new account you will be asked for the email address you wish to use and the password. The email must be an existing one but the password can be anything you wish. (choose something nice and secure). If you don't have an email address click Get an email address link and you will be able to create a Microsoft email account.

As part of the sign up process you will need to enter your first and last name.

If you created a new account with your existing email address you will be asked to verify the email exists by clicking on a link in your email. If however you chose to create a new Microsoft email account you will be asked to enter the CAPTCHA characters on the screen to prove you aren't a robot.

Once you have either signed in or created a new Microsoft account you will be taken to the payment page. Even if you are just trying Office 365 out you will be asked for payment details and it is up to you to cancel the subscription after the free month.

Payments can be made via Paypal or by credit card.
