Just bought Microsoft 365 and not sure what to do next? This guide explains the Microsoft365.com/setup steps in simple words. You will learn how to sign in, add your product key and install the apps on your device.
Microsoft365.com/setup is the page where you add your Microsoft 365 product key to your Microsoft account. After that, you can install apps like Word, Excel, PowerPoint and Outlook.
You usually need this page when you buy a Microsoft 365 product key card, or when you get a product key in an email from a store.
Keep these things ready:
Your 25-character product key (it is on the card or in your purchase email)
A Microsoft account (you can create one during setup)
A steady internet connection
A Windows or Mac computer, or a phone or tablet that supports the apps
Enough free space on your device
Open your web browser and go to the Microsoft365.com/setup page.
Sign in with your Microsoft account. If you do not have one, choose the option to create a new account.
Enter your 25-character product key when the page asks for it.
Check your country or region and your language, then continue.
Follow the steps on the screen to finish adding the product key to your account.
Go to your Microsoft account page and open the Services & subscriptions section.
Select Install next to Microsoft 365.
Open the downloaded file and let the install finish.
Open an app like Word and sign in with the same account.
The steps can look a little different from time to time, so always follow what you see on the screen.
On a card: Look at the back of the card. You may need to gently scratch off the silver area.
In an email: Search your inbox for the message from the store where you bought it.
In your store account: Some stores show the key under your orders.
Type the key carefully. Letters like O and 0 (zero) can look alike.
Sign in to your Microsoft account and open Services & subscriptions.
Select Install.
Open the downloaded file when it finishes.
Wait for the apps to install and do not turn off your computer.
Open Word or Excel and sign in to start using them.
Sign in to your Microsoft account and open Services & subscriptions.
Select Install and open the downloaded file.
Follow the steps to move the apps to your Applications folder.
Open an app and sign in with your Microsoft account.
Check the product key. Make sure every character is correct.
Check your internet. A weak connection can stop the page from loading.
Try another browser. Chrome, Edge and Firefox are all fine.
Sign out and sign in again. This solves many small problems.
Clear your browser data. Old saved data can cause errors.
Check if the key was already used. A product key can usually be added to one account only.
Restart your device. Then try the steps again.
Remove old Office versions. An older version can block a new install.
Use only Microsoft’s own website to enter your product key.
Check the web address carefully before you sign in.
Never share your password or product key with anyone.
Be careful with pages that ask for payment just to add a key you already own.
Do not trust pop-ups or messages that say your computer has a problem and ask you to call a number.
Keep your apps updated to get the latest features and security fixes.
