Set up Office 365 Professional Plus – Sign in & Install
This guide walks you step by step through signing in with the credentials you received by email and installing Office. Your subscription is already included in the account – you do not need a product key or phone activation.
Step by step: Sign in & Install
Open the sign-in page
In your browser, open login.microsoftonline.com and enter the email address you received from us by email.
Click Next and enter the password
Click Next. Then enter the password you received and click Next again.
Update password (required on first login)
On your first sign-in, Microsoft requires you to change the password. Fill in the fields as described below and then click Sign in.

Stay signed in
When asked “Stay signed in?”, click Yes so you don't have to sign in again every time you open Office.
Open the app launcher & “More apps”
You now see the main Microsoft 365 interface. Click the grid icon at the top left (app launcher) and then “More apps”.

Install app – Microsoft 365 Apps
Click “Install app” at the top right, then choose “Microsoft 365 Apps”.

Install Office
On the account page, click “Install Office”. The download of the installer starts. Open the downloaded file and follow the instructions to install Office.

After installation
After installation, open e.g. Word and sign in with the account you received: File → Account → Sign in. This links Office to your subscription and fully activates it.
Already have a Microsoft account? Add a second account
If you already use a Microsoft account in Office, you can easily add the new Office 365 account as well. In Word or Excel, open File → Account and select “Switch account” or “Sign in with a different account”. Add the new Office 365 account there. You can switch between accounts at any time.
Direct download
Alternatively, you can download the installer directly:
