Signing up for Microsoft 365 takes less than ten minutes, and by the end of it you’ll have access to Word, Excel, PowerPoint, Outlook, Teams, 1 TB of OneDrive storage, and much more. This guide walks you through every step — from visiting the Microsoft website to launching your first app — so you can get productive as quickly as possible.
You don’t need to install anything to get started. All Microsoft 365 plans include free access to the web versions of Word, Excel, PowerPoint, OneNote, and other apps at office.com. Simply sign in with your Microsoft account and start working directly in your browser — no download required.

​
Before You Begin: What You Need

Before signing up, make sure you have the following ready:
  • A Microsoft account — this is a free account tied to an email address (e.g. your Outlook, Hotmail, Gmail, or any other email). If you don’t have one yet, you’ll create it during sign-up.
  • A payment method — a credit card, debit card, or PayPal account for paid plans. You won’t be charged until your free trial ends if you choose that option.
  • A compatible device — Windows 10/11 or macOS 10.14 or later for desktop apps; iOS 16+ or Android 10+ for mobile apps.

Step-by-Step: Signing Up for Microsoft 365

1

Go to the Microsoft 365 website

Open your browser and navigate to microsoft.com/microsoft-365. This is the official Microsoft 365 homepage where you can browse all available plans, compare features, and start your purchase.
2

Choose 'Buy now' or 'Try free for 1 month'

On the plans page, you’ll see pricing cards for Personal, Family, and Business plans. Each card has two options:
  • Try free for 1 month — available on most personal and business plans. You’ll need to enter payment details but won’t be charged until the trial period ends.
  • Buy now — skips the trial and starts your paid subscription immediately.
Click whichever option suits you on your chosen plan.
If you start a free trial, make sure you complete your full setup — including installing the apps and activating your subscription — before the 30-day trial ends. If you don’t cancel before the end of the trial, Microsoft will automatically charge your payment method for the first month or year. Set a calendar reminder so you don’t forget.

Select your plan

If you haven’t already chosen a plan, you’ll be prompted to pick one:
  • Microsoft 365 Personal — for one person, up to 5 devices
  • Microsoft 365 Family — for up to 6 people, each with their own account and storage
  • Microsoft 365 Business Basic / Standard / Premium — for organisations needing business email, Teams, and more
You can also choose monthly or annual billing on this screen. Annual billing typically saves you around 15–20% compared to paying month to month.

Confirm your subscription and activate

After payment, Microsoft sends a confirmation email to your Microsoft account address. Open that email and click the confirmation link if prompted.You’ll then land on the Microsoft 365 setup page (or you can visit office.com and sign in). Here you can:
  • Launch web apps immediately from your browser
  • Download and install the desktop apps for Windows or Mac
  • Get the mobile apps for iOS or Android
Your subscription is now active. The next section covers installation in detail.

​
Installing Microsoft 365 Apps

Once your subscription is active, you can install the full desktop apps on up to 5 PCs or Macs per user.
Installing on Windows 10 or Windows 11:
  1. Go to office.com and sign in with your Microsoft account.
  2. Click Install apps in the top-right corner of the page.
  3. Select Microsoft 365 apps from the dropdown menu.
  4. A file called OfficeSetup.exe (approximately 4 MB) will download.
  5. Open the downloaded file. The Office installer launches and downloads the full app suite in the background — this typically takes 5–15 minutes depending on your internet speed.
  6. Once complete, open any app (e.g. Word) from the Start menu.

Managing Your Subscription

Once you’re signed up, you can manage everything from your Microsoft account dashboard.

View or change your plan

Visit account.microsoft.com/services to see your current plan, billing date, and payment method. You can upgrade, downgrade, or cancel at any time.

Share with family members

If you have Microsoft 365 Family, go to account.microsoft.com/family to invite up to 5 other people. Each person gets their own separate account and 1 TB of OneDrive storage.

Manage installed devices

In your Microsoft account, under Devices, you can see which devices have Microsoft 365 installed and deactivate a device remotely to free up an installation slot.

Download Office apps anytime

Return to office.com at any time to re-download the installer — useful if you get a new computer or need to reinstall after a system reset.
If you signed up through the Apple App Store or Google Play Store, your subscription is managed through that platform — not directly through Microsoft. To cancel or change your plan, you’ll need to do so through your Apple ID settings or Google Play subscriptions page.
